Sulphate-reducing bacteria (SRB) are anaerobic microorganisms that use sulphate as a
terminal electron acceptor in, for example, the degradation of organic compounds. They are …

Recent advances in molecular biology have extended our understanding of the metabolic
processes related to microbial transformation of petroleum hydrocarbons. The physiological …

Deltaproteobacteria, now proposed to be the phyla Desulfobacterota, Myxococcota, and
SAR324, are ubiquitous in marine environments and play essential roles in global carbon …

Dissimilatory sulphate reduction is the unifying and defining trait of sulphate-reducing
prokaryotes (SRP). In their predominant habitats, sulphate-rich marine sediments, SRP have …

Life evolved and flourished in the absence of molecular oxygen (02). As the 02 content of
the atmosphere rose to the present level of 21% beginning about two billion years ago …

A unique characteristic in the prokaryotic world is the multiplicity of life strategies without any
involvement of oxygen. Actually, life in anoxic habitats is prokaryotic to a large extent …
