Query: NC_011663:4579777 Shewanella baltica OS223 chromosome, complete genome
Lineage: Shewanella baltica; Shewanella; Shewanellaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This genus includes species that inhabit a wide range of environments and are capable of utilizing a wide variety of electron acceptors during anaerobic respiration including some insoluble metal oxides while using very few carbon sources such as lactate or acetate. This group of organisms have been studied extensively for their electron transport systems. This species is differentiated from other Shewanella spp based on its ability to grow at 4 degrees C but not at 37 degrees C, production of N-acetyl-beta-glucosaminidase, lack of chymotrypsin, and ability to use a variety of complex carbon compounds as carbon and energy sources.
Subject: NC_011901:837085 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.
