1. Introduction

In the context of rapid societal progress, microorganisms are experiencing a remarkable surge in their applications across diverse industries, encompassing food, pharmaceuticals, energy, and agriculture. Notably, their pivotal role in bioremediation, which involves the utilization of microorganisms to restore polluted environments, cannot be overstated. In modern society, microorganisms have emerged as indispensable assets, effectively meeting the escalating demand for microbial products.

To fully harness the potential of microorganisms and address the increasing demand, the cultivation of superior strains has become imperative in the realm of microbial applications [1]. Various methods are employed to breed microbes, including natural screening, gene recombination, mutation breeding, metabolic control breeding, and genetic engineering breeding [2,3,4]. Among these methods, mutation breeding induces various biological effects, such as base deletion, chromosome breakage, and gene recombination, leading to altered traits in the offspring and the introduction of numerous mutations [5,6].

In particular, directional screening serves as a valuable supplementary tool for mutagenesis breeding, enabling the swift identification of desired target traits and facilitating the acquisition of microbial strains possessing the desired characteristics. Such traits can greatly benefit the microbial strain, resulting in improved qualities like higher yields, increased resistance to environmental stress, and enhanced nutritional values. It is worth noting that genetic modification techniques have emerged as powerful tools for agriculture and biotechnology applications.

Mutation breeding commonly employs two main approaches: physical mutagenesis and chemical mutagenesis [7]. Physical mutagenesis involves subjecting organisms to high-energy radiation, such as gamma rays, X-rays, UV light, neutrons, ion beams, beta particles, alpha particles, and plasma [8]. These forms of radiation induce genetic mutations by causing DNA damage. On the other hand, chemical mutagenesis involves the use of various chemicals to induce genetic changes. Chemical mutagens can damage DNA through processes like alkylation or the formation of base compounds [9]. Examples of chemical mutagens include alkylating agents, natural base analogs, lithium chloride, nitroso compounds, azides, base analogs, antibiotics, hydroxyamine, and acridine.

However, both radiation (e.g., X-ray and γ-ray) and chemical mutagenesis methods exhibit certain limitations. Radiation mutagenesis suffers from challenges in accurately controlling dosage and yields a low mutation rate. Furthermore, the generation of radiation necessitates bulky and costly equipment, specialized operational expertise, and additional safety precautions to restrict its usage. On the other hand, chemical mutagenesis, despite offering a higher mutation frequency, generates toxic agents that are arduous to eliminate, thereby posing substantial risks to both users and the environment.

Against this backdrop, atmospheric and room-temperature plasma (ARTP) has emerged as an innovative and efficient physical mutagenesis method. The ARTP system was originally developed by the Department of Chemical Engineering at Tsinghua University and subsequently commercialized by Si Qing Yuan Biotechnology (now Tmax Tree Co., Ltd., Jiangsu, China). Following its commercialization, the research team at Tsinghua University conducted comprehensive investigations into the mutagenesis mechanism, confirming the exceptional mutagenic efficiency of this technology through extensive fundamental studies [10,11]. ARTP surpasses traditional chemical and radiation mutagenesis by inducing high DNA damage and offering a greater diversity of mutations [12]. Moreover, it proves effective at creating mutations in genes that are difficult to target using other methods. Additionally, ARTP enables the creation of mutations in multiple genes simultaneously, facilitating faster and more efficient gene editing. Notably, the primary gas used in ARTP systems is helium, and it does not generate hazardous materials [13].

1.1. Principle of ARTP

ARTP technique has garnered considerable attention for its capacity to induce mutations in microorganisms. Operating at atmospheric pressure and temperatures ranging from 25 to 40 °C, ARTP generates plasma jets consisting of helium atoms, oxygen atoms, nitrogen atoms, and OH radicals. Plasma is commonly referred to as the “fourth state” of matter, in addition to solid, liquid, and gas. Extensive studies have revealed that the active particles present in plasma can cause structural changes to microbial cells and membrane walls, resulting in damage to microbial genes and significant alterations in their sequence and metabolism [14].

ARTP offers several advantages over traditional mutagenesis methods. Firstly, it inflicts substantial damage to DNA, resulting in a high mutation rate in microorganisms. The resulting mutations can be inherited by subsequent generations, giving rise to stable mutant strains (Figure 1) [10]. Moreover, ARTP outperforms molecular biology technologies, in terms of simplicity, cost-effectiveness, and the absence of hazardous or damaging chemicals.

The ARTP technology serves as a mutagenesis method based on discharged plasma. Within the ARTP system, high-purity helium gas (≥99.99%) is ionized by an externally applied RF electric field, leading to the formation of a non-thermal plasma jet downstream of the plasma nozzle exit [5]. These high-energy and highly reactive particles, including excited helium atoms, oxygen atoms, nitrogen atoms, and OH radicals, transiently irradiate microorganisms, leading to genetic variation and mutation. The active energy particles in ARTP cause damage to the genetic material of microbial strains and induce the initiation of the SOS repair mechanism in biological cells [15,16]. SOS repair is a mechanism prone to errors, involving mismatch repair and recombination repair, which give rise to diverse mismatched sites and ultimately stabilizes genetic alterations, leading to the emergence of mutant strains. SOS repair preserves genome integrity and enhances cell survival. The intensity of SOS repair is intricately linked to the magnitude of DNA damage. The UMU-test method shows that ARTP has significant effects on the genetic material of organisms, with a rich range of damage mechanisms, especially on the genetic material of eukaryotes such as chromosomes [12]. Therefore, ARTP exhibits improved mutagenic performance and a broader range of applications than other mutagenesis methods. Genomic sequencing reveals that mutant strains obtained through ARTP mutagenesis have a greater number of gene mutation sites [17]. This highlights the potential of ARTP as a valuable tool for genetic research and breeding purposes.

1.2. Technical Parameters

The applicability of ARTP mutagenesis to various microorganisms allows for a wide range of parameter combinations. The key parameters and their importance are summarized as follows: First, strain vitality: opt for strains in the logarithmic growth phase as the mutagenesis material, as cells proliferate rapidly and are more sensitive to external environmental factors during this growth stage [18]. Second, cell concentration: select an appropriate concentration of cell suspension for mutagenesis. Third, mutagenesis dose: The ARTP mutagenesis dose is closely related to the mutagenesis time. Typically, the mutagenesis dose that leads to a 90% cell death rate is used as a parameter, as it results in a relatively high forward mutation rate [19]. Fourth, subsequent dilution: to fully utilize the agar plate surface and obtain single, dispersed colonies, properly dilute the treated cell suspension and then spread it evenly on the agar plate surface. Lastly, screening method: Different colony screening methods can be chosen based on the specific research objectives. For instance, Yu et al. [20] developed a high-throughput screening method, utilizing streptomycin resistance prescreening and a 24-well deep well plate/microplate reader rescreening strategy, to identify a high-yield neomycin sulfate mutant strain from a large number of mutants. Subsequently, through fermentation condition optimization, the neomycin sulfate concentration of the strain Sf6-2 was increased by 100%. Similarly, Yao et al. [21] identified 10 high-yield tylosin-producing strains from a mutant library of S. fradiae using a high-throughput 24-well plate screening method and UV spectrophotometry. Further, re-screening in shake flasks led to the identification of two strains with significantly higher tylosin A production than the wild-type strain. The optimization of these parameters is crucial for achieving successful ARTP mutagenesis, obtaining desired mutations, and effectively harnessing the potential of this technique for microbial breeding.

1.3. Mutagenesis Targets

The utilization of ARTP in mutagenesis holds great potential for producing superior strains of microorganisms with enhanced traits. This technique has demonstrated its effectiveness across various microorganism groups, including bacteria [22], fungi [23], and microalgae [24]. The success of ARTP can be contributed to several key factors, including its high efficiency in inducing mutations, its capacity to cause diverse genetic damage, and its operation under mild and safe conditions (Figure 2).

Through the application of ARTP, researchers can introduce specific changes to the genetic material of microorganisms, leading to the development of desirable traits. This method has proven particularly advantageous in improving critical microbial characteristics, such as increased product yield, enhanced stress tolerance, or optimized metabolic pathways. Consequently, mutagenic strains present a promising option for the industrial production of various desirable active substances. This article provides a concise overview of the applications and future prospects of ARTP technology in the breeding of microorganisms.

ARTP technology has emerged as a powerful tool for enhancing enzyme production and optimizing biocatalyst production. In the context of chitosan oligosaccharides production, ARTP has effectively been used to generate mutant strains of Bacillus cereus, resulting in increased chitosanase yield and activity [25]. Chitosanase, a crucial enzyme found in microorganisms, breaks down chitosan into smaller chitosan oligosaccharides, which possess valuable antimicrobial, antioxidant, and anti-inflammatory effects, making them promising for various applications [26].

Moreover, ARTP has played a pivotal role in obtaining high-yield thermostable protease-producing strains, such as Bacillus licheniformis TP1-5, which exhibit significantly enhanced enzyme activity compared to the original strain [27]. These thermostable proteases, known for their stability and activity at high temperatures, have practical applications in industries such as high-temperature washing, medicine, and leather production.

In addition to proteases, ARTP has been instrumental in improving Coenzyme Q10 (CoQ10) production in Rhodobacter sphaeroides [28,29,30,31,32]. Coenzyme Q10, an essential dietary supplement, plays a vital role in antioxidant processes and bioenergy generation. By employing ARTP mutagenesis and subsequent selection of mutant strains, the production efficiency of Coenzyme Q10 was significantly improved, achieving an impressive efficiency of 80.38%.

Furthermore, ARTP has been utilized to generate mutant strains of alkaline phosphatase-producing bacteria, such as Bacillus amyloliquefaciens S-52 [33]. The alkaline phosphatase activity of the mutant strain S-52 was determined to be 12,110.6 U/L, which is 4.67 times greater than that of the original strain. ARTP has also been employed in the production of other enzymes, such as protease [34,35], alginate lyase [36], α-amylase [37], and alkaline protease [38]. The mutant strains exhibited significantly higher enzyme production capacity compared to the original strain, demonstrating the effectiveness of ARTP in improving enzyme yield.

In conclusion, the applications of ARTP technology in enzyme production have shown promising results in various microbial strains. Its potential in enhancing enzyme yields, improving activity, and optimizing production processes has significant implications for diverse industries, contributing to advancements in biocatalysts and enzyme-based products. As ARTP continues to evolve and gain momentum, its integration into enzyme engineering and biotechnology promises to unlock new avenues for sustainable and efficient enzyme production.

Extensive research has showcased its versatile application in improving the production of specific amino acids, including poly-γ-glutamic acid (PGA), L-serine, L-glutamine, L-histidine, and L-isoleucine.

PGA, a biopolymer composed of glutamic acid monomers, exhibits diverse biological activities, and ARTP-induced mutations have successfully led to significant increases in poly-glutamic acid synthesis, enabling cost-effective production [39]. Similarly, L-serine, an essential amino acid with crucial roles in physiological processes and overall health, has benefited from ARTP technology, with researchers achieving notable improvements in L-serine production compared to parent strains [40].

The demand for L-glutamine, another essential amino acid, has prompted efforts to enhance its production using ARTP-mediated approaches. Liang et al. [41] combined mutagenesis with metabolic engineering to optimize L-glutamine production, presenting potential advantages across various applications. Additionally, Lv et al. [42] employed ARTP and gene editing techniques to develop a highly productive strain, CGQ03/pXMJ19-R5-glnA^Sc-ppk^Ec, derived from Corynebacterium glutamicum ATCC 14,067. Firstly, the strain ATCC 14,067 underwent ARTP mutagenesis, resulting in the isolation of a mutant strain designated as N01, which exhibited a significantly increased yield of L-glutamine. Subsequently, gene editing techniques, such as gene knockout and overexpression, were applied to manipulate essential genes involved in the L-glutamine metabolic pathway. These genetic modifications facilitated the enhancement of L-glutamine production in the strain CGQ03/pXMJ19-R5-glnA^Sc-ppk^Ec. The engineered strain exhibited remarkable L-glutamine yields, reaching up to 73.5 ± 3.1 g/L, representing a substantial improvement compared to the parent strain.

Moreover, ARTP technology has been successfully applied to induce mutations in Corynebacterium glutamicum strains, resulting in the development of mutant strains with heightened production of other amino acids such as L-histidine [43] or L-isoleucine [44].

The availability of high-quality amino acids holds immense value for the industrial and pharmaceutical sectors. By leveraging the power of metabolic engineering and ARTP technology, researchers can significantly enhance amino acid yields and optimize strain metabolic performance, effectively meeting the escalating demands of diverse industries. In conclusion, ARTP technology has emerged as a highly promising tool for enhancing amino acid synthesis in bacteria. Its successful application to improving the production of specific amino acids, including PGA, L-serine, and L-glutamine, presents an economically viable and sustainable approach to amino acid production, effectively catering to the needs of various sectors. The integration of metabolic engineering with ARTP technology further amplifies the potential for optimizing amino acid yield and strain performance, paving the way for novel advancements in this field.

2.3. Antibiotics Overproducers

ARTP technology has found extensive application in the production of antibiotics, particularly in the development of bacteriocins, which are biologically active peptides or proteins synthesized by ribosomes. Bacteriocins exhibit strong inhibitory effects against competing species and possess broad-spectrum antibacterial activity [45,46,47]. Through a combined mutagenesis approach, multiple high-yielding bacteriocin mutant strains were developed from Lactobacillus plantarum, with production enhancements ranging from 103.48% to 551% [48,49,50].

In the case of dalbavancin, a lipoglycopeptide antibacterial agent effective against various Gram-positive organisms, including those with multidrug resistance [51], researchers employed a composite mutagenesis approach combining UV and ARTP. The aim was to enhance the yield of the dalbavancin precursor in Nonomuria spp. Wang et al. [52] utilized the strain DW-3-19 as the initial strain and subjected it to UV mutagenesis under specific conditions, resulting in the isolation of the DW-4-127 mutant strain. The fermentation process of DW-4-127 exhibited a 33.5% enhancement in the production of the dalbavancin precursor compared to the starting strain. Subsequently, the mutant strain DW-4-127 underwent ARTP mutagenesis and was subjected to selection using 0.6 mg/L of streptomycin as the screening agent, leading to the acquisition of the high-yield strain DW-5-52. The dalbavancin precursor production of DW-5-52 demonstrated a significant 23.9% increase compared to DW-4-127 and an impressive 68.7% improvement compared to the starting strain. Furthermore, strain DW-5-52 exhibited favorable genetic stability.

Through mutagenesis and screening approaches, researchers can obtain mutant strains with enhanced antibiotic production and activity, thereby improving efficiency and yield in antibiotic production. As a result, ARTP technology holds great promise in the creation of more efficient and high-quality antibiotics, effectively addressing the growing demand in the medical and pharmaceutical sectors.

Continued improvement and optimization of ARTP technology will drive further innovation and progress in the field of antibiotic production. By leveraging ARTP’s capabilities, researchers can contribute to the development of novel antibiotics that are more effective, safer, and capable of avoiding antibiotic resistance, thus benefiting global healthcare and public health.

[53] utilized Bacillus amyloliquefaciens A3 as a wild-type strain, which produces lipopeptide biosurfactant, to enhance biosurfactant production through ARTP mutagenesis, aiming to remove petroleum hydrocarbons from soil. In soil column leaching experiments, they achieved 45.44% removal of petroleum hydrocarbons by modifying relevant enzyme activities.

Similarly, Bao et al. [22] discovered Bacillus velezensis LYB-23, a chromium-resistant bacterium, from waste chromium residues. Employing the synergistic approach of domestication and ARTP technology, they successfully elevated the minimum inhibitory concentration of B. velezensis for chromium from 80 mg/L in the original strain to 400 mg/L in the mutant strain. This groundbreaking method significantly augmented the bacteria’s tolerance to Cr (VI) and improved its efficiency in reducing and absorbing this pollutant, showcasing its potential for breeding bacteria tailored for environmental remediation applications.

Furthermore, Yang et al. [54] isolated Pseudomonas fluorescein, a bacterium capable of producing extracellular polymeric substances (EPS), from soil. Harnessing ARTP technology, they obtained a mutant strain, named T4-2, with substantially enhanced EPS production and improved flocculating activity. The EPS generated by T4-2 showed a high adsorption capacity for chromium (VI) and has great potential for efficiently removing cadmium from contaminated soil or lake water, offering a promising solution for environmental remediation.

The utilization of ARTP technology in environmental remediation showcases its efficacy in enhancing pollutant degradation capabilities and tolerance of bacterial strains. This advancement provides opportunities to improve the efficiency and effectiveness of the environmental remediation processes, ultimately contributing to a cleaner and healthier environment.

2.5. Others

Its role in agriculture and the breeding of resistant bacteria is also noteworthy. Plant growth-promoting (PGP) bacteria, which offer eco-friendly alternatives to chemical fertilizers, have been a focus of research in this regard.

For instance, Wang et al. [55] isolated Pantoea sp. YSD J2 from Cyperus esculentus L. var. sativus and employed ARTP mutagenesis to enhance indole-3-acetic acid (IAA) and organic phosphorus (lecithin) concentrations by 42.06% and 34.15%, respectively. Another PGP endophyte, YSD YN2, isolated from the same plant, exhibited improved seed germination and plant growth as a result of ARTP mutagenesis [56].

In the realm of antibacterial activity, ARTP-mediated genetic modification of Limsolactobacillus reuteri produced the AR-148 mutant strain [57], whose cell-free supernatant (MCFS) demonstrated potent antibacterial activity against Escherichia coli. MCFS disrupted cell membranes, altered biomolecules and enzyme levels, and impacted genes related to energy metabolism, oxidative stress, and cell integrity. This study sheds light on the antibacterial mechanism of MCFS against Gram-negative bacteria, presenting potential applications in the food industry.

Moreover, the ARTP-induced mutation of Bacillus mucilaginosus resulted in the strain BM-50, which exhibited a twofold increase in acid production capacity, leading to a 15.3% enhancement in vanadium leaching efficiency from stone coal [58]. Additionally, ARTP is employed to boost bacterial primary metabolites and generate resistant strains [59,60], further highlighting its potential as an efficient mutagenesis strategy for improving microbial performance in various industrial applications.

These findings underscore the versatility and efficacy of ARTP technology in enhancing microbial traits and performance for a wide range of applications, including agriculture, environmental remediation, and industrial processes.

ARTP mutagenesis of this strain has resulted in numerous strains with a high production of specific compounds, including astaxanthin [63,64], lycopene [65], squalene [66], and p-coumaric acid (p-CA) [67]. Additionally, ARTP has been used to obtain fermentation strains with special robustness and high ethanol production [75], as well as strains with low acetaldehyde content [81] and acid tolerance [79].

Moreover, ARTP mutation technology has found applications in yeast genome functional research and genetic engineering. It enables the production of a large number of yeast mutants, allowing for the investigation of gene expression, metabolic pathways, and their interrelationships. For example, Cai et al. [67] identified the association of the HTZ1 gene with tyrosine biosynthesis in Saccharomyces cerevisiae. Through gene knockout and ARTP mutagenesis, they obtained high-producing tyrosine mutants and conducted genome and transcriptome analysis to reveal the underlying mechanism behind the increased tyrosine production. Similarly, ARTP mutagenesis was used to generate a yellow X. dendrorhous mutant and the GATA transcription factor XdWC2 was identified as crucial in controlling astaxanthin production [74]. This research laid the foundation for understanding the global regulation of astaxanthin biosynthesis and guiding the development of high-yield astaxanthin-producing strains.

The application of ARTP technology in yeast research and applications has driven significant progress, enabling the generation of diverse mutants with improved traits and shedding light on the mechanisms underlying gene expression and metabolic pathways. These advancements have broad implications for various fields of study and hold promise for further advancements in yeast-related research and applications.

3.2. Application to Mold Mutation

The application of ARTP technology in molds primarily focuses on inducing mutations and improving strains. By subjecting molds to ARTP, which can cause genetic mutations or variations, desirable changes in the strains can be achieved, such as increased product yield, development of functional strains and enhanced resistance (Table 2). This technology holds significant implications in various industries.

For instance, Wang et al. [82] employed ARTP and UV mutagenesis to introduce modifications in S. peucetius SIPI-11 and enhance the production of doxorubicin. Through screening in a doxorubicin (DXR) medium, a mutant strain (S. peucetius 33–24) with a remarkable DXR yield of 570 mg/L was identified, surpassing the wild-type strain’s yield of 119 mg/L. ARTP has also been effectively applied to other antibiotic-producing strains, such as natamycin [83], avilamycin [84], salinomycin [85], wuyiencin [86], and ansamitocin [87].

Additionally, ARTP mutagenesis has yielded mutant strains with improved production of diverse bioenzymes. For instance, naringinase, an enzyme with wide applications in the food, beverage, and pharmaceutical industries, saw significant productivity increases through UV-ARTP mutagenesis in Aspergillus tubingensis MN589840. High-yield mutants U1, A6, and UA13 exhibited impressive productivity enhancements [88]. Furthermore, ARTP has been successfully utilized for the production of diverse bioenzymes, including tannase [89,90], raw starch-degrading enzymes [91], thermostable xylanase [92], cellulose [93,94] and L-asparaginase [95].

ARTP mutagenesis of Myrothecium verrucaria has shown effectiveness in producing enzymes that efficiently remove environmental pollutants and reduce their toxicity [96,97]. Additionally, ARTP technology has demonstrated promise in agricultural yield improvement. Strains of Aspergillus niger v. Tiegh subjected to ARTP mutagenesis were identified as capable of efficiently degrading soil phosphorus compounds. Among them, xj120-12 is a highly efficient phosphorus-solubilizing and growth-promoting strain, significantly enhancing plant growth and yield through effective degradation of phosphorus compounds [100].

Furthermore, ARTP has opened avenues for developing biocontrol agents. Qiu et al. [98] successfully used ARTP technology to obtain fungal strains with high biocontrol potential, such as Beauveria bassiana. These mutant strains exhibit stronger biocontrol abilities, improved growth characteristics, and enhanced enzyme activities, making them potential biocontrol tools in complex agricultural environments.

ARTP technology is a valuable tool for enhancing filamentous fungi, inducing beneficial mutations, and improving desirable traits in mold strains. Its success is evident in increased enzyme production, enhanced lycopene synthesis, and the generation of resistant strains with improved biocontrol abilities. The application of ARTP in mold research opens new opportunities in microbial metabolic engineering and offers innovative approaches to strain improvement and utilization in various fields.

3.3. Application to Edible Fungi

ARTP technology is extensively applied in the breeding of edible mushrooms, which are valuable food and medicinal fungi known for their high nutritional and medicinal value. Through the use of ARTP technology, it becomes possible to modify the growth traits, yield, and quality of edible mushrooms, thereby increasing their economic worth and market competitiveness (Table 2).

For example, ARTP technology has been utilized to induce gene mutations and increase the content of flavonoids in Phellinus baumii [104]. Following ARTP mutagenesis and subsequent screening, a total of four mutants with high flavonoid production were obtained. Among these mutants, A67 exhibited the highest flavonoid yield, with an impressive 88.24% increase in intracellular flavonoid production. In addition to obtaining high-flavonoid-producing mutants, strains subjected to ARTP mutagenesis also yielded exceptional strains with elevated production of laccase [105], polysaccharide [106,107,108,109,110], and hispidin [111].

The fruit bodies of edible mushrooms hold significant value as both food and medicinal products. The economic worth of these fruit bodies is closely tied to their yield and quality. To enhance these characteristics, ARTP serves as an efficient mutagenesis tool that can induce mutations and then select strains with exceptional traits in mushroom resource breeding, making them more competitive in the market [112,113,114,115]. By utilizing ARTP mutagenesis, it becomes possible to enhance specific characteristics of strains, thereby endowing them with unique functionalities. For instance, Zhang et al. [116] employed 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging capacity to screen a total of 14 mutants of Ganoderma lucidum with a robust antioxidant capacity from a pool of 103 mutants generated through ARTP. Through comprehensive antioxidant evaluation analysis, two mutant strains with remarkable antioxidant capacity were successfully identified.

As ARTP technology continues to advance and improve, its applications in edible mushroom breeding and improvement are expected to expand further. This technology holds great promise for enhancing the traits and characteristics of edible mushrooms, ultimately contributing to the development of more productive and high-quality mushroom varieties.

Through ARTP mutagenesis, microalgae can be engineered to produce valuable compounds, including biofuels [117], pigments [118,119], lipids [120], and omega-3 fatty acids [121,122] (Table 3).

Mutagenesis induces alterations in metabolic pathways, enzyme activities, and regulatory mechanisms, resulting in increased product yields. One notable advantage of ARTP mutagenesis is its efficiency and rapidity in improving microalgae strains. Compared to traditional breeding methods, which rely on labor-intensive and time-consuming techniques for generating mutations, ARTP mutagenesis significantly shortens the timeframe. Fang et al. [123] utilized ARTP to induce mutations in Spirulina, with the goal of enhancing its carbohydrate yield and growth rate. From a mutant library, they screened and selected ideal mutants with increased carbohydrate content and growth rate.

Moreover, ARTP mutagenesis provides valuable insights into the synthesis mechanisms of microalgal target compounds, which underlie strain improvement. By analyzing transcriptomic and proteomic data, researchers can identify differentially expressed genes and proteins linked to increased productivity. Chen et al. [124] identified a mutant strain of Schizochytrium limacinum LD11 with high docosahexaenoic acid (DHA) production through ARTP mutagenesis. Molecular analysis revealed the underlying mechanisms responsible for the improved DHA yield in the mutant strain, thus enabling further breeding strategies for enhanced DHA production in Schizochytrium.

In conclusion, ARTP mutagenesis is a valuable tool in microalgal biotechnology, facilitating the generation of mutant libraries, accelerating strain improvement, and unraveling molecular mechanisms related to increased productivity. As ARTP technology continues to advance and integrates with other omics approaches, further breakthroughs can be anticipated in optimizing microalgae for sustainable production of valuable compounds.
