bacteria, including the sulfide-oxidizing bacteria Thiobacilli and Acidimicrobium ferrooxidans, are the base of the food web of this cave (Roach et al.
The strong dominance of olenids in sea-floor environments that were poor in oxygen but rich in sulphur suggested to Fortey (2000) that they may have been chemoautotrophic
The effect of 2-chloro, 6-(trichlormethyl) pyridine on the chemoautotrophic
metabolism of nitrifying bacteria.
From volcanic origins of chemoautotrophic
life to Bacteria, Archaea, and Eukarya.
In this study, the double domain BMC protein CsoS1D from the chemoautotrophic
sulfur bacterium Halothiobacillus neapolitanus was expressed recombinantly and used to generate a polyclonal antibody.
microbes (bacteria and archaea) have been found in deep-ocean sediments and at hydrothermal vents, where hot water flows out through newly formed volcanic rock at mid-ocean ridges.
Evidence for chemoautotrophic
symbiosis in a Mediterranean cold seep clam (Bivalvia: Lucinidae): comparative sequence analysis of bacterial 16S rRNA, APS reductase and RubisCO genes.
Robinson (2005) notes that the earliest and most basic forms of life forms are the Archaea (most chemoautotrophic
single-celled organisms which are very resistant and can thrive in harsh conditions), Bacteria (single-celled organisms with complex cell walls) and Eukaryotes (organisms made up of cells with nuclei, that is, their DNA is walled off in a separate compartment of the cell).

Prokaryotes, and from Prokaryotes to Nucleated Cells," Philosophical Transactions of the Royal Society B: Biological Sciences 358 (2003): 59-85.
Consequently, since we had found that chemoautotrophic
nitrification was the predominant nitrifying process in these acid pasture soils (Islam et al.
They present different feeding modes (carnivores, herbivores, omnivores, deposit-feeders, symbiotic chemoautotrophic
bacteria), this plasticity could be the reason of their success in many environments (Beesley et al.
In Thiobacillus ferrooxidans, an acidophilic chemoautotrophic
bacterium sensitive to mercury ions, a group of mercury-resistant strains, which volatilize mercury, has been isolated.
