Special Issue Information

Dear Colleagues,

This Special Issue will explore the diversity of microorganisms in different environments, including soil, air, water, foods, contact surfaces, animals, and the human gut. Microorganisms’ ability to survive, adapt, and undertake critical metabolic processes within these environments, from food processing/fermentation to the regulation of biogeochemical cycles and bioremediation, product formulation, plant growth promotion, soil fertility, and associations with living animals, is testament to their resilience. Exploring the range of microbial groups in different environments and their diversity and impacts, including metabolic processes, could enable a better understanding of the intricate nature of these organisms and their possible applications.

For this Special Issue, researchers are invited to contribute articles on microbial diversity and the impacts of climate change, the environment, and geochemical processes on microflora in different environments and ecosystems. Articles focusing on the use of modern molecular tools to explore microbial diversity are encouraged, including the metagenomic analysis of diverse microbial niches and population genetics and its determinants. These can include studies on microbial diversity and succession in different processes and their possible modulation/use for the benefit of humans and the environment, such as in fermentation, biomining, bioremediation, immune system modulation, and antimicrobials. Overall, this Special Issue will present new discoveries, methodologies, processes, and applications related to microbial diversity.

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.

Vegetable crops such as tomato are highly susceptible to various pathogens. Nanoparticles (NPs) are emerging as effective nano-bactericides for managing plant pathogens. Communities of rhizosphere bacteria are essential for plant physiological health and also serve as a critical factor in evaluating the environmental compatibility of NPs. We evaluated the effects of a nano-bactericide (Cu-Ag nanoparticles) and a commercial bactericide (thiodiazole–copper) on the rhizosphere microbiome of tomato. The results show that low and high doses of the two bactericides induced alterations in the bacterial community structure to differing extents. Cu-Ag nanoparticles increased the relative abundance of potentially beneficial bacteria, including Bacteroidota, Gemmatimonadota, Acidobacteriota, and Actinobacteriota. Functional prediction revealed that Cu-Ag nanoparticles may affect the metabolic pathways of tomato root rhizosphere microorganisms and regulate the lacI/galR family, which controls virulence factors and bacterial metabolism. This study provides insight into the influence of metal nanoparticles on plant rhizosphere microbiomes and may lay a foundation for the application of nano-bactericides for the environmentally friendly control of plant diseases.
