Query: NC_008340:480399 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.

General Information: This organism is associated with severe and chronic periodontal (tissues surrounding and supporting the tooth) diseases. Progression of the disease is caused by colonization by this organism in an anaerobic environment in host tissues and severe progression results in loss of the tissues supporting the tooth and eventually loss of the tooth itself. The black pigmentation characteristic of this bacterium comes from iron acquisition that does not use the typical siderophore system of other bacteria but accumulates hemin. Peptides appear to be the predominant carbon and energy source of this organism, perhaps in keeping with its ability to destroy host tissue. Oxygen tolerance systems play a part in establishment of the organism in the oral cavity, including a superoxide dismutase. Pathogenic factors include extracellular adhesins that mediate interactions with other bacteria as well as the extracellular matrix, and a host of degradative enzymes that are responsible for tissue degradation and spread of the organism including the gingipains, which are trypsin-like cysteine proteases.
