Special Issue Information

Dear Colleagues,

Environmental pollution, exacerbated by the ever-increasing population, is one of the most pressing challenges facing the world today. For instance, industrial effluents, agricultural runoff and urbanization have led to widespread contamination of air, water and soil. Available traditional remediation methods are often costly, with a negative environmental impact and limited long-term effectiveness. Thus, there is a need to continually improve processes such as bioremediation, which utilizes live microorganisms and plants to either degrade or transform pollutants, and ultimately offer a sustainable, environmentally friendly solution.

In this Special Issue, the emphasis is on the application of microorganisms and plants, as well as the role of bioinformatics and omic technologies in improving bioremediation processes. This includes the exploration of new research in microbial communities, metabolic pathways, and genetic engineering. Through this, we aim to tackle pollutants such as heavy metals, organic contaminants, and emerging pollutants.

The Special Issue invites submissions that cover a wide range of topics, including the following: advances in the use of microorganisms for the degradation or transformation of environmental pollutants; the role of phytoremediation and other plant-based strategies in the removal of pollutants from contaminated environments; and the application of genomics, transcriptomics, and proteomics to study microbial communities and metabolic pathways.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The present study evaluated the effect of two inoculum concentrations on the degradation of crude oil by Corynebacterium stationis CsPe-1. To this end, two treatment systems were utilized, each containing Davies Minimum Medium, 1% crude oil, and bacterial inoculum at concentrations of 10% and 15%, respectively. The degree of oil biodegradation was determined by evaluating the biochemical oxygen demand (BOD5), the chemical oxygen demand (COD), the concentration and fractions of oil and grease, and the total petroleum hydrocarbons (TPH). The results indicated that both BOD5 and COD exhibited an increase after a 20-day treatment period. For the 10% and 15% inoculum concentrations, a statistically significant difference was observed between the initial and final values of oils and fats (p < 0.05). In both systems, the levels of oils and fats decreased by 61%, contrasting with the control system, which exhibited minimal variation. A significant difference (p < 0.05) was observed in the degradation of TPH at the two inoculum concentrations. The findings indicated that the biodegradation of TPH was more efficient with an inoculum of 15%, resulting in a 79.94% reduction in fraction 3 (28–40 carbon chains). Fraction 1 exhibited less degradation, attributable to the toxicity of short-chain n-alkanes. Genomic analysis identified the pcaG and pcaH genes, which have been linked to the degradation of polycyclic aromatic hydrocarbons. This study underscores the biotechnological potential of strain CsPe-1 for the remediation of hydrocarbon-contaminated environments, thereby contributing to the realization of Sustainable Development Goals 14 and 15.
