Query: NC_008340:362000 Alkalilimnicola ehrlichei MLHE-1, complete genome
Lineage: Alkalilimnicola ehrlichii; Alkalilimnicola; Ectothiorhodospiraceae; Chromatiales; Proteobacteria; Bacteria
General Information: This chemoautotrophic strain was isolated from Mono Lake in California, which contains arsenic and has high pH and salt concentrations. Arsenite-oxidizing bacterium. Alkalilimnicola ehrlichei is capable of growth with arsenite [As(III)] as the electron donor with nitrate as electron acceptor. It may be responsible for production of arsenate [As(V)] in anoxic lake bottom.
Subject: NC_014836:1180454 Desulfurispirillum indicum S5 chromosome, complete genome
Lineage: Desulfurispirillum indicum; Desulfurispirillum; Chrysiogenaceae; Chrysiogenales; Chrysiogenetes; Bacteria
General Information: Environment: Fresh water; Temp: Mesophile. This is the first cultured species of the proposed new genus "Desulfurispirillum", and the sequencing of its genome will expand the range of experimental approaches that researchers can use to characterize its metabolic pathways for energy production and understand how these pathways are regulated. This organism is notable for its ability to reduce selenate to selenite and further to insoluble elemental selenium, in a process called dissimilatory selenate reduction.
