Special Issue Information
Dear Colleagues,
Multiple anthropogenic activities contribute to the contamination and degradation of ecosystems, threatening good environmental status and human health, and calling for urgent, effective, and sustainable remediation solutions.
The chemical contamination of the ecosystems represents a major concern, leading to detrimental consequences at different levels of biological organization. However, the effects on the diversity and ecological function of microbial assemblages are still largely unknown, which limits our understanding of the impact of different types of contaminants on overall ecosystem functioning.
In addition, deepening our knowledge on the diversity and metabolic pathways of microbes inhabiting contaminated sites can unveil novel taxa (either as single strains or consortia) with biotechnological potential for the bioremediation of harmful pollutants. Indeed, bioremediation approaches based on the stimulation of useful autochthonous microbes (biostimulation) or the addition of useful microbes (bioaugmentation) are gaining increasing attention for their eco-compatibility and lower costs. For effective bioremediation, ideal microbes should be abundant and metabolically active in the natural system, resistant to mixed contaminations, easy to grow, and responsive to selective stimulation. However, frequent failures are observed due to unsuccessful increases in the abundance or activity of target microbes, or due to the low fitness of lab-grown microbes once released into the contaminated environment. It is thus important to improve our knowledge on the diversity and dynamics of natural microbial assemblages for optimizing bioremediation performance, especially in sites that show the co-presence of multiple contaminants.
This Special Issue calls for papers covering the following topics:
- Next-generation sequencing studies on the diversity and function of microbes (including bacteria, archaea, microbial eukaryotes, and their viruses) in contaminated sites;
- Studies on the potential of contaminants to act as drivers of microbial assemblage diversity and/or functioning in ecosystems, and the possible use of microbes as pollution bioindicators/biosensors;
- Experimental studies on the effects of contamination on microbes and on the use of microbes for the bioremediation of contaminated ecosystems;
- Microbial/microbiome engineering to boost the bioremediation of contaminated sites;
- Understanding the mechanisms of microbial-mediated bioremediation and synergic interactions between different microbes that can enhance bioremediation yields;
- Emerging pollutants and possible microbial-mediated bioremediation approaches for their removal/detoxification;
- Microbial products useful for the bioremediation of contaminated sites (biosurfactants, siderophores, enzymes, metallothioneins, phytochelatins, EPS, etc.)
- Studies covering aspects related to this Special Issue, even if not included above.

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.
