“To test the theory of a chemoautotrophic origin of life in a volcanic, hydrothermal setting, we explored mechanisms for the buildup of bio-organic compounds by carbon fixation on catalytic transition metal precipitates.”
“Nitrification, a chemoautotrophic process, is carried out by a consortium of bacteria and involves production of intermediates such as nitrite (NO2 -), and nitrous oxide (N2O) as a byproduct.”
“Another pathway of N2 production is the anaerobic ammonium oxidation (anammox; NH4++ NO2 - → N2 + 2H2O) which, in contrast to denitrification, is carried by chemoautotrophic bacteria.”
“If one hazards a guess from other chemoautotrophic-based systems, the fact that the cave is said to be where seas were would suggest that the bacteria could be utilizing hydrocarbons.”

“Symbiosis with chemoautotrophic bacteria has, so far, not been proved for Vesicomya and the genus is not restricted to sulphide-rich reducing habitats.”
“On the origins of cells: a hypothesis for the evolutionary transitions from abiotic geochemistry to chemoautotrophic prokaryotes, and from prokaryotes to nucleated cells.”
