Almost the entire seafloor is covered with sediments that can be more than 10 000 m thick
and represent a vast microbial ecosystem that is a major component of Earth's element and …

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

Biological oxidation of hydrogen sulfide to sulfate is one of the major reactions of the global
sulfur cycle. Reduced inorganic sulfur compounds (referred to below as sulfur) are …

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 …

Campylobacter jejuni is currently the leading cause of bacterial gastroenteritis in humans.
Comparison of multiple Campylobacter strains revealed a high genetic and phenotypic …

Recent biochemical and genomic data differentiate the sulfur oxidation pathway of Archaea
from those of Bacteria. From these data it is evident that members of the Alphaproteobacteria …

In marine systems, nitrate is the major reservoir of inorganic fixed nitrogen. The only known
biological nitrate-forming reaction is nitrite oxidation, but despite its importance, our …

Hydrogen sulfide (H2S) and methane (CH4) are produced in anoxic environments through
sulfate reduction and organic matter decomposition. Both gases diffuse upwards into oxic …

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

Cytochromes c are among the most studied proteins. This is possibly due to their relatively
high thermodynamic stability and their red color, which makes protein purification easier. 1 …
