Navy's advanced tethered vehicle (ATV dive #118) and found a persistent community composed of filamentous sulfur bacteria (Beggiatoa sp.), vesicomyid clams (Vesicomya/Calyptogena spp.), mytilids (Idas sp.), limpets (Pyropelta spp., Cocculina sp.), snails (Mitrella sp.), and polynoid polychaetes (Bathykurila sp.).
Autotrophic sulfide-oxidizing bacteria of the genus Beggiatoa (Nelson et al, 1989) that grow in dense mats on the sediment surface assimilate [CO.sub.2] from seawater and sediments; the latter [CO.sub.2] pool includes contributions from sulfate reduction and methane oxidation.
The cuttings contained high hydrocarbon concentrations and were anoxic with a surface mat of Beggiatoa. Surprisingly, there was no [H.sub.2]S odor either at the surface or within the cuttings pile.

Several strains of sulfur bacteria, such as Beggiatoa and Thiothrix have been detected in wastewater.
The primary producers are chemolithotrophic bacteria, both aerobic (Beggiatoa) and anaerobic, that oxidize the hydrogen sulphide in the water and use the energy obtained to fix carbon.
Thiothrix and Beggiatoa participated in the creation of Cesspool cave, Virginia, through sulphur oxidation.
Uno de los tipos microbianos mas abundantes de los sulfureta, especialmente en las interfases en las que entran en contacto el [H.sub.2]S y los sulfuros con el gas [O.sub.2] atmosferico, son las bacterias oxidadoras de azufre reducido deslizantes del genero Beggiatoa. La Fig.
