Query: NC_007205:499808 Candidatus Pelagibacter ubique HTCC1062, complete genome
Lineage: Pelagibacter ubique; Pelagibacter; Pelagibacteraceae; Rickettsiales; Proteobacteria; Bacteria
General Information: They were originally named SAR11 and known only from their rRNA genes, which were first identified in environmental samples from the Sargasso Sea in 1990. P. ubique are possibly the most numerous bacteria in the world.
Subject: 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.
