Special Issue Information

Dear Colleagues,

Specialized metabolites, formerly (or usually) called secondary metabolites, toxins, secondary products, or natural products, are organic compounds produced by any lifeform, e.g. bacteria, fungi, animals, or plants, which are not directly involved in the normal growth, development, or reproduction of the organism. This Special Issue will only focus on microbial specialized metabolites, fully in line with Microorganisms ISSN 2076-2607 aims and scope (over 7,700 articles published since 1996, on October 17, 2022). Please have a look there: https://www.mdpi.com/search?q=&journal=microorganisms&sort=pubdate&page_count=50. Bacterial production of secondary metabolites starts in the stationary phase as a consequence of lack of nutrients or in response to environmental stress. Secondary metabolite synthesis in bacteria is often described as not essential for their growth, however, they allow them to better interact with their ecological niche. The main synthetic pathways of secondary metabolite production in bacteria are b-lactam, oligosaccharide, shikimate, polyketide and non-ribosomal pathways. Aspects about microbial specialized metabolites under consideration for publication in this Special Issue are listed below (non-exhaustive list, please contact the Guest Editor for any additional information):

  • Specialized metabolites from bacteria, yeasts, fungi
  • Analytical techniques for full chemical description of microbial specialized metabolites
  • Transfer of plant specialized metabolites to microbial platforms
  • Bioprospecting for new microbial specialized metabolites
  • Subcellular localization of microbial specialized metabolites
  • Machine learning discovery of missing links in microbial specialized metabolites biosynthesis
  • Specialized metabolites of endophytes
  • Cryptic specialized metabolites and how to reveal and express the genes coding for
  • Mining biosynthetic gene clusters for new microbial specialized metabolites

  • Engineering powerful green cell factories for robust microbial specialized metabolites production
  • Specialized metabolite biosynthetic diversity encoded in microbial genomes
  • Optimization of microbial specialized metabolites production in fermenters (fermenter design, pO2, pH, nutrients, agitation speed…); idem in Erlenmeyer flasks, microplates, photobioreactors, etc
  • Excretion or in situ cell storage of microbial specialized metabolites
  • Bottleneck removal of microbial specialized metabolites biosynthetic pathways
  • CRISPR-Cas9 based genetic engineering of microbial specialized metabolites biosynthetic pathways

Current Insights in Fungal Importance—A Comprehensive Review

Besides plants and animals, the Fungi kingdom describes several species characterized by various forms and applications. They can be found in all habitats and play an essential role in the excellent functioning of the ecosystem, for example, as decomposers of plant material for the cycling of carbon and nutrients or as symbionts of plants. Furthermore, fungi have been used in many sectors for centuries, from producing food, beverages, and medications. Recently, they have gained significant recognition for protecting the environment, agriculture, and several industrial applications. The current article intends to review the beneficial roles of fungi used for a vast range of applications, such as the production of several enzymes and pigments, applications regarding food and pharmaceutical industries, the environment, and research domains, as well as the negative impacts of fungi (secondary metabolites production, etiological agents of diseases in plants, animals, and humans, as well as deteriogenic agents).

Substantial progress has been achieved and knowledge gaps addressed in synthetic biology-mediated engineering of biological organisms to produce high-value metabolites. Bio-based products from fungi are extensively explored in the present era, attributed to their emerging importance in the industrial sector, healthcare, and food applications. The edible group of fungi and multiple fungal strains defines attractive biological resources for high-value metabolites comprising food additives, pigments, dyes, industrial chemicals, and antibiotics, including other compounds. In this direction, synthetic biology-mediated genetic chassis of fungal strains to enhance/add value to novel chemical entities of biological origin is opening new avenues in fungal biotechnology. While substantial success has been achieved in the genetic manipulation of economically viable fungi (including Saccharomyces cerevisiae) in the production of metabolites of socio-economic relevance, knowledge gaps/obstacles in fungal biology and engineering need to be remedied for complete exploitation of valuable fungal strains. Herein, the thematic article discusses the novel attributes of bio-based products from fungi and the creation of high-value engineered fungal strains to promote yield, bio-functionality, and value-addition of the metabolites of socio-economic value. Efforts have been made to discuss the existing limitations in fungal chassis and how the advances in synthetic biology provide a plausible solution. Full article

Weeds such as parasite plants are one of the most serious pests that farmers are forced to combat since the development of agriculture using different methods including mechanic and agronomy strategies. These pests have generated significant losses of agrarian and herding production, constituting a serious impediment for agricultural activities in reforestation practices and in important infrastructures. All these serious problems have induced the expansive and massive use of synthetic herbicides, which represents one of the main cause of environmental pollution, as well as serious risks for human and animal health. An alternative environmental friendly control method could be the use of bioherbicides based on suitably bioformulated natural products, of which the main ones are fungal phytotoxins. This review covers the literature from 1980 to the present (2022) and concerns fungal phytotoxins with potential herbicidal activity in order to obtain their efficacy as bioherbicides for practical application in agriculture. Furthermore, some bioherbicides based on microbial toxic metabolites are commercially available, and their application in field, mode of action and future perspectives are also discussed.
