Special Issue Information
Ionizing radiation affects cellular biomolecules including nucleic acids, proteins, and lipids directly or indirectly, eventually leading to lesions that can express themselves in a variety of biologically significant changes. Interestingly, microorganisms exhibiting high radiation resistance have been isolated from a wide range of environmental conditions, even though a naturally radiation intensive environment has not been found. Since Deinococcus radiodurans, one of the most radiation-resistant bacteria, was first isolated in 1956 from X ray-irradiated canned meat, the radiation-resistant microorganisms have been discovered in the three domains of life (Bacteria, Archaea, and Eukarya). These organisms are not only extremely tolerant to ionizing radiation, but also other DNA damaging agents and oxidative stress-generating conditions, such as desiccation. Therefore, characterization of the molecular mechanisms and key players underlying the multiple stress resistance helps us to understand their mysterious survival strategy and sheds lights on the biotechnological application of these strategies and their useful molecules, such as enzymes, polysaccharides, metabolites, etc. This Special Issue of Microorganisms calls for reviews as well as original research articles concerning any aspect related to radiation-resistant microorganisms, from the physiology and molecular biology to the applied aspects of radiation-resistant microorganisms.

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.
