Special Issue Information
Dear Colleagues,
Our planet is saturated with microbes; with approximately 5.0×1030 cells on our planet, the number of microbes is around 108 greater than the number of stars in the observable universe. Microbes constitute an entire world unseen by the naked eye. However, the processes performed by microbes in this invisible world, due to their great abundance, remarkable metabolic capacities, and adaptation potential, significantly affect our visible world. These processes include virtually every chemical reaction in the biosphere that constitutes the main biogeochemical cycles (carbon, nitrogen, sulfur), which are the primary materials on our planet and are necessary for all life. The role of microorganisms in the primary biogeochemical cycles of terrestrial, freshwater, and marine ecosystems is presented. Consequently, they are believed to be key players in the adaptation, control, and recovery of our ecosystems.
The biodiversity of microorganisms is highlighted, and their metabolic pathways based on exchanges and biotransformation of the elements (carbon, nitrogen, sulfur) within ecosystems need to be discussed. The impacts of human activities on the microbial actors and processes of biogeochemical cycles, as well as the cascading ecological effects (greenhouse gas emissions, acid rains, dystrophic crises, etc.), also need to be discussed.
The processes also involve interactions between organisms, both among microbes and between microbes and large organisms in biogeochemical cycles. These interactions are further affected by changes in climate. Therefore, we need to explore this world, the creatures that inhabit it, and the things they do.

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. Life 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 2600 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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
