Query: NC_002570:126500 Bacillus halodurans C-125, complete genome
Lineage: Bacillus halodurans; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Strain C-125 (JCM9153) was isolated in 1977 and is the most well studied alkaliphilic Bacillus organism. Alkaliphilic bacterium. This organism is similar to Bacillus subtilis but is alkaliphilic, grows poorly at neutral pH, and very well at pH >9.5. This bacterium produces a peptidoglycan that contains teichuronic peptides consisting of polyglutamic and polyglucuronic acids that counteract the halophilic environment.
Subject: NC_007722:55558 Erythrobacter litoralis HTCC2594, complete genome
Lineage: Erythrobacter litoralis; Erythrobacter; Erythrobacteraceae; Sphingomonadales; Proteobacteria; Bacteria
General Information: This strain was collected from the Sargasso Sea at a depth of 10 meters. Phototrophic bacterium. Organisms in this aerobic phototrophic genus are found in marine environments. Members of this group produce bacteriochlorophyll a, which is normally found in anaerobic organisms. One theory to explain this is that the anoxygenic photosynthetic gene cluster was acquired by these organisms via lateral gene transfer. Although they require an organic carbon substrate for growth, they are able to supplement a significant fraction of their metabolic requirements with photosynthetically derviced energy. This species was isolated from a marine cyanobacterial mat. Although they require an organic carbon substrate for growth, they are able to supplement a significant fraction of their metabolic requirements with photosynthetically derviced energy. The presence of the carotenoids bacteriorubixanthinal and erythroxanthin sulfate give this organism a reddish color.
