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

Isoprenoid quinones are one of the most important groups of compounds occurring in
membranes of living organisms. These compounds are composed of a hydrophilic head …

A critical step in the biogeochemical cycle of sulfur on Earth is microbial sulfate reduction,
yet organisms from relatively few lineages have been implicated in this process. Previous …

Lithotrophic sulfur oxidation is an ancient metabolic process. Ecologically and taxonomically
diverged prokaryotes have differential abilities to utilize different reduced sulfur compounds …

Sulfur (S) is a crucial component in the environment and living organisms. This work is the
first attempt to provide an overview and critical discussion on the roles, mechanisms, and …

Chemolithotrophic bacteria that use sulfate as terminal electron acceptor (sulfate-reducing
bacteria) constitute a unique physiological group of microorganisms that couple anaerobic …

The number of sequenced genomes of sulfate reducing organisms (SRO) has increased
significantly in the recent years, providing an opportunity for a broader perspective into their …

Life is the harnessing of chemical energy in such a way that the energy-harnessing device
makes a copy of itself. This paper outlines an energetically feasible path from a particular …

Phototrophic sulfur bacteria are characterized by oxidizing various inorganic sulfur
compounds for use as electron donors in carbon dioxide fixation during anoxygenic …

Behind the versatile nature of prokaryotic energy metabolism is a set of redox proteins
having a highly modular character. It has become increasingly recognized that a limited …
