Query: NC_011060:514874 Pelodictyon phaeoclathratiforme BU-1, complete genome
Lineage: Pelodictyon phaeoclathratiforme; Pelodictyon; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria
General Information: Pelodictyon phaeoclathratiformeBU-1 was isolated from lake water in 1989. This organism is a phototrophic green sulfur bacteria that inhabits hydrogen sulfide-containing water and freshwater mud, brackish waters and marine environments. This organism forms net-like microcolonies and contains gas vescicles. It is believed that the gas vesicles provide the buoyancy necessary to keep the cell at the optimal depth for photosynthesis.
Subject: 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.
