Query: NC_015760:8914 Streptococcus salivarius CCHSS3, complete genome
Lineage: Streptococcus salivarius; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: The commensal bacterium Streptococcus salivarius is predominant specie of the human oropharyngeal tract and exerts an important role in oral ecology. Streptococcus salivarius is an aerobic, gram-positive coccus. This organism is the most common organism isolated from the human oral cavity. Streptococcus salivarius can also be an opportunistic pathogen causing endocarditis, blood infection, and peritonitis. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes.
Subject: NC_007481:3167434 Pseudoalteromonas haloplanktis TAC125 chromosome I, complete
Lineage: Pseudoalteromonas haloplanktis; Pseudoalteromonas; Pseudoalteromonadaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: This strain was isolated from a sample of coastal sea water near a French Antarctic station. This organism is adapted to growth at low temperatures and reactive oxygen species by a number of putative dioxygenases and fatty acid desaturases amongst other proteins. The organism can grow optimally in salt concentrations of 1.5 to 3.5% NaCl.The genome consists of 2 chromosomes, one of which may replicate unidirectionally. Some interesting features of this genome include the lack of the nucleoid-associated gene hns, a lack of genes involved in molybdopterin metabolism, a lack of the cAMP-CAP complex, and a lack of the PEP-dependent PTS system.
