Query: NC_005090:1921154 Wolinella succinogenes DSM 1740, complete genome
Lineage: Wolinella succinogenes; Wolinella; Helicobacteraceae; Campylobacterales; Proteobacteria; Bacteria
General Information: Cow rumen bacterium. Wolinella succinogenes is most commonly isolated from the bovine rumen and is considered nonpathogenic, however, this organism has also been isolated from the human gingiva and dental root canal infections.
Subject: NC_011901:3072817 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.
