Thiobacillus ferrooxidans is an acidophilic chemoautotrophic bacterium sensitive to mercury ions that is used industrially in leaching metals from a variety of ores.
Here sulfide-rich effluents support dense communities of free-living bacteria, as well as tube worms and mollusks living in symbiosis with chemoautotrophic bacteria (internal bacteria that fix organic carbon using chemical energy from reduced compounds such as sulfide).
Carboxysomes are biological nanoreactors in some photo- and chemoautotrophic prokaryotes which can transform inorganic C[O.
Moreover, larvae transported by bottom currents within the rifts would also be under the influence of fallout from the plume (which also travels along the rift valley) and would be expected to have an isotopic composition that reflected the chemoautotrophic sources of production at the vents.
Carboxysomes are polyhedral bodies found in cyanobacteria and in chemoautotrophic bacteria.
Most chemoautotrophic bacteria and all cyanobacteria contain carboxysomes, polyhedral inclusion bodies that enhance the fixation of carbon dioxide by ribulose-1,5-bisphosphate carboxylase/oxygenase.
Evidence of chemoautotrophic primary production at deep-sea vents and seeps and ultrastructural and enzymatic studies of mussel gill tissue led to the conclusion that bathymodiolin mussels depend on chemoautotrophic endosymbiotic bacteria (thiotrophic and/or methanotrophic, Cavanaugh 1983, Fisher et al.
To date, little information exists about the anoxia tolerance in animals that harbor symbiotic chemoautotrophic bacteria inside their tissues.
