Special Issue Information

Dear Colleagues,

This Special Issue focuses on the role of microorganisms in advancing sustainable solutions for resource recovery and environmental restoration. It highlights cutting-edge research exploring microbial-driven processes for recovering valuable resources (e.g., metals, nutrients, bioenergy) from waste streams, as well as bioremediation strategies to mitigate pollution in soil, water, and air. 

We invite contributions on topics including but not limited to:

  • Bioleaching and metal recovery;
  • Microbial degradation of pollutants;
  • Waste treatment and resource utilization;
  • Cross-disciplinary innovations in environmental microbiology;
  • Microbial resource recovery;
  • Environmental bioremediation;
  • Bioenergy production and nutrient recycling;
  • Sustainable bioprocesses and circular economy solutions;
  • Applications of synthetic biology and systems biology in environmental sustainability.

This Special Issue aims to showcase innovations that bridge microbiology and sustainability, fostering dialogue among researchers, policymakers, and industries to accelerate the transition toward a greener future.

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. Microorganisms is an international peer-reviewed open access monthly 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 2700 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.

Phosphate tailings are usually rich in phosphorus and some other mineral nutrients, which is very suitable for composting. In this study, 60 days of composting using phosphate tailings, chicken manure, and straw resulted in a significant decrease in total nitrogen (TN) content from 1.75 ± 0.12 g/kg to 0.98 ± 0.23 g/kg (p < 0.01), with a nitrogen retention of 56%, an increase in water-soluble phosphorus (Ws-P) from 3.24 ± 0.14 mg/kg to 7.21 ± 0.09 mg/kg, and an increase in immediate potassium (AK) from 0.56 ± 0.21 mg/kg to 1.90 ± 0.11 mg/kg (p < 0.05). Metagenomic sequencing showed little changes in the diversity and abundance of microbial communities before and after composting, but changes in species composition and the abundance of archaea, bacteria, and fungi resulted in differences in community structure before and after composting. Composting contributed to a lower gene abundance of ARGs and MRGs. The addition of phosphate tailings combined the functions of chemical regulation and nutrient enrichment, and its synergistic effect significantly optimized the nutrient cycling in the composting system.
