Query: NC_011901:2202690 Thioalkalivibrio sulfidophilus HL-EbGr7 chromosome, complete

Lineage: Thioalkalivibrio sulfidophilus; Thioalkalivibrio; Ectothiorhodospiraceae; Chromatiales; Proteobacteria; Bacteria

General Information: Obligately chemolithoautotrophic, haloalkaliphilic, mesophilic, microaerophilic and sulfur-oxidizing bacterium. Uses CO2 as a carbon source and reduced inorganic sulfur compounds as an energy source. Utilizes ammonium and urea, but not nitrate or nitrite, as a N-source. Isolated from a full-scale Thiopaq bioreactor in the Netherlands used to remove H2S from biogas. Thioalkalivibrio species are commonly isolated from soda lakes and tend to dominate the microbial community of hypersaline soda lakes. These organisms have a pH optimum of 10 and are able to oxidize hydrogen sulfide to elemental sulfur. Thioalkalivibrio species have also been isolated from sulfide oxidizing bioreactors which remove sulfide from refinery and natural gas.

Subject: NC_004757:2730057 Nitrosomonas europaea ATCC 19718, complete genome

Lineage: Nitrosomonas europaea; Nitrosomonas; Nitrosomonadaceae; Nitrosomonadales; Proteobacteria; Bacteria

General Information: Ammonia-oxidizing bacterium. This organism is an obligate chemo-lithoautotroph as it only uses ammonia and carbon dioxide and mineral salts for growth, and is an important part of the global biogeochemical nitrogen cycle. It can derive all energy requirements from the oxidation of ammonia to nitrate, driving global nitrogen from the reduced insoluble form to the oxidized and potentially gaseous form (including NO and NO2 which are greenhouse gases). The energy derived from ammonia oxidation is in turn used to drive carbon fixation. This bacterium also provides plants with a readily available form of nitrogen, is important in wastewater treatment, and may be involved in bioremediation of sites contaminated with toxic compounds.
