The Diversity of Microorganisms from Extreme Marine Environments

Dear Colleagues,

Marine hydrothermal sources associated with oceanic ridges and submarine volcanic activities represent extreme ecosystems characterized by unique physicochemical parameters, including complex variations in pH, temperature, and hydrostatic pressure. Despite these challenging conditions, these environments emerge as remarkable oases of life within the globally oligotrophic ocean. Microbial communities play a crucial role as primary producers in these intricate ecological systems. The current scientific understanding of microbial diversity and metabolic processes in these environments remains limited, presenting significant opportunities for innovative research. Of particular scientific interest are the complex interactions that occur both between the microorganisms themselves and between microorganisms and mineral substrates, each representing a distinct avenue for groundbreaking discoveries. By systematically investigating these two types of interactions, researchers can deepen our understanding of microbial communication, cooperation, and competition, as well as the mechanisms by which microbes colonize, transform, and adapt to mineral surfaces. Together, these insights advance knowledge of microbial adaptation, metabolic strategies, and ecological dynamics in some of the planet’s most challenging marine environments.

The proposed Special Issue of Microorganisms aims to provide a comprehensive contemporary overview of microorganism research in extreme marine environments. Manuscripts addressing multifaceted aspects of taxonomic and functional diversity analyses, detailed investigations of microorganism interactions with their surrounding environment, and characterization of novel metabolic pathways are welcome. These studies may utilize diverse methodological approaches, including analyses of model microbial strains and advanced metagenomics techniques.

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 250 words) can be sent to the Editorial Office for assessment.

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.
