Special Issue Information

Dear Colleagues,

This Special Issue is a continuation of our 2021 Special Issue, "Interaction between Inorganic Pollutants and Microbiota in the Environment". (https://www.mdpi.com/journal/microorganisms/special_issues/Microbiota_Inorganic_Pollutants).

There is a growing demand for understanding the interaction between inorganic pollutants and microbiota in the environment. Inorganic pollutants, originating from both natural sources and anthropogenic processes, reach the biosphere where microbiota play a primary role in their fate. Furthermore, inorganic contaminants can alter microbial habitats and thereby impact the ability of the microbiota to perform their natural function. Common examples of inorganic pollutants include heavy metals, halides, oxyanions and cations, inorganic nanoparticles, and radionuclides. Microbial transformation mostly affects their mobilization or immobilization in the environment, as many of these pollutants are not biodegradable. These reactions can lead to the movement of inorganic pollutants between different phases of the biosphere, such as from the hydrosphere to the lithosphere and vice versa, as well as emission to the atmosphere. Recent advances in understanding microbiota in the environment using -omics methods (metagenomics, metatranscriptomics, proteomics, and metabolomics) allows for an unprecedented understanding of the interactions between microbiota and inorganic pollutants. The Special Issue aims to collect cutting-edge studies on this subject—in particular, to provide a holistic view of the microbial processes affecting the fate of inorganic pollutants in the environment and the effect of these chemicals on native microbial communities’ structure and functions.

Papers will be selected by peer review, with the expected outcome being the wide dissemination of research results. Original research articles and review articles on the above aspects of inorganic pollutants in the environment are of interest.

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.

Increased nitrogen (N) input from natural factors and human activities may negatively impact the health of marsh wetlands. However, the understanding of how exogenous N affects the ecosystem remains limited. We selected the soil bacterial community as the index of ecosystem health and performed a long-term N input experiment, including four N levels of 0, 6, 12, and 24 gN·m−2·a−1 (denoted as CK, C1, C2, and C3, respectively). The results showed that a high-level N (24 gN·m−2·a−1) input could significantly reduce the Chao index and ACE index for the bacterial community and inhibit some dominant microorganisms. The RDA results indicated that TN and NH4+ were the critical factors influencing the soil microbial community under the long-term N input. Moreover, the long-term N input was found to significantly reduce the abundance of Azospirillum and Desulfovibrio, which were typical N-fixing microorganisms. Conversely, the long-term N input was found to significantly increase the abundance of Nitrosospira and Clostridium_sensu_stricto_1, which were typical nitrifying and denitrifying microorganisms. Increased soil N content has been suggested to inhibit the N fixation function of the wetland and exert a positive effect on the processes of nitrification and denitrification in the wetland ecosystem. Our research can be used to improve strategies to protect wetland health. Full article
