Of the sox genes, seven genes, soxXYZABCD, code for periplasmic proteins responsible for the oxidation of sulfur compounds (hydrogen sulfide, elemental sulfur, thiosulfate and sulfite) (Rother, 2001). Potential energy sources for deep-sea vent chemoautotrophy include reduced sulfur compounds, molecular hydrogen, reduced metals and ammonium.
Most of the ocean is devoid of ferrous iron, due to both the oxidative effect of dissolved oxygen in the water and the tendency of bacteria to take up the iron.
In addition, geochemical thermodynamic models have not been completely verified based on actual microbiological community structures and activities (Takai, 2006b). Pyrococcus furiosus is an aquatic anaerobic hyperthermophiles archaeon first isolated in a hydrothermal vent near Vulcano Island, Italy.

There are four major pathways for CO2 fixation, i.e. Four major pathways of CO2 fixation.
The stable carbon isotopic fractionations between CO2 and biomass by this pathway have been determined to be in the range 4.8â26.7â° (House, 2003). Chemoautotrophs are organisms that are able to fix inorganic carbon using a chemical energy obtained through the oxidation of reduced compounds.
