Special Issue Information

Dear Colleagues,

Environmental pollutants can exert selective stresses on living organisms. Among environmental stressors, metal(loid)s are of special relevance as some of the most abundant, toxic, and persistent inorganic pollutants. Metal(loid) toxicity can arise from interaction with biomolecules, such as proteins or nucleic acids, whose native structure and function may be thereby altered. Likewise, metal(loid)s can produce oxidative stress giving rise to very toxic reactive oxygen species. Both, prokaryotic and eukaryotic microorganisms have evolved a range of mechanisms to reduce the metal(loid) toxicity, such as chelation or intracellular sequestration (bioaccumulation) of metal(loid) cations by specific oligopeptides (glutathione, phytochelatins) or proteins (metallothioneins), metal(loid) exclusion by blocking the usual access “gate” to the cell, metal(loid) exclusion by active export (efflux pump) from the cell, extracellular sequestration or biosorption (passive adsorption by extracellular polymers), metal(loid) biotransformation (redox chemistry or methylation), and/or bioprecipitation by excreted cellular metabolism products. In this Special Issue of Microorganisms, we invite you to send contributions concerning any aspect related with this topic, including genetic, physiological, molecular, and cell biology or ecological aspects of the microbial stress response to metal(loid)s.

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 papers will be 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 1000 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.
