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

Sulfur-driven autotrophic denitrification refers to the chemolithotrophic process coupling
denitrification with the oxidation of reduced inorganic sulfur compounds. Ever since 1904 …

Genus assignment is fundamental in the characterization of microbes, yet there is currently
no unambiguous way to demarcate genera solely using standard genomic relatedness …

Background Acidithiobacillus ferrooxidans is a major participant in consortia of
microorganisms used for the industrial recovery of copper (bioleaching or biomining). It is a …

The phylogeny of the large bacterial class Gammaproteobacteria has been difficult to
resolve. Here we apply a telesco** multiprotein approach to the problem for 104 diverse …

Rubisco is the predominant enzymatic mechanism in the biosphere by which autotrophic
bacteria, algae, and terrestrial plants fix CO2 into organic biomass via the Calvin–Benson …

Bacteriophages are realized to be numerous and important components of oceanic food
webs principally because of their lytic capabilities. The subtle changes that temperate …

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

The mechanisms by which bacterial cells generate helical cell shape and its functional role
are poorly understood. Helical shape of the human pathogen Helicobacter pylori may …

Deep-sea vents support productive ecosystems driven primarily by chemoautotrophs.
Chemoautotrophs are organisms that are able to fix inorganic carbon using a chemical …
