Chemolithotrophic Microorganisms

Dear Colleagues,

Chemoautotrophic microorganisms are widely distributed in natural and manmade ecosystems. They not only drive the element biogeochemical cycles on Earth, but also play important roles in bioremediation; however, due to the long generation times, extreme sensitivity to environmental factors, and close relationships with other microbes, chemoautotrophic microorganisms are usually difficult to isolate and cultivate in the laboratory, making many of them uncultivated and even unknown. Though some meta-omic technologies are now popularly used to obtain their genomes or predict their functions at the genomic and transcriptomic scales, studies at the cellular level and in pure culture are also essential to reveal the pathways involved in the biogeochemical cycles and screen some excellent strains for the bioremediation of pollutants in the environment.

The aim of this Special Issue is to collect some of the latest works in the field of chemoautotrophic microorganisms. It welcomes studies on (1) the enrichment, isolation, and characterization of chemoautotrophs; (2) (meta)genomic-, (meta)transcriptomic-, and/or (meta)proteomic-scale-based functional analyses of chemoautotrophs; (3) microbial interactions between chemoautotrophs and other microbes; and (4) the strategies or methods that are optimized to obtain chemoautotrophs from the environment.

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.
