Query: NC_008260:1044440 Alcanivorax borkumensis SK2, complete genome
Lineage: Alcanivorax borkumensis; Alcanivorax; Alcanivoracaceae; Oceanospirillales; Proteobacteria; Bacteria
General Information: This bacterium was isolated from a seawater sediment sample in the North Sea. The species is able to use Mihagol-S (C14,15-n-alkanes) as a principal carbon source. Using n-alkanes as a sole carbon source causes the strains to produce extracellular and membrane-bound surface-active glucose lipids. Phenotypic analysis showed a restricted nutritional profile, high halotolerance, the absence of fermentative metabolism, and a low G+C content. This, in combination with a 16S phylogenetic study, allowed the placing of this organism into a new genus.
Subject: 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.
