Query: NC_009785:1895679 Streptococcus gordonii str. Challis substr. CH1, complete genome

Lineage: Streptococcus gordonii; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria

General Information: Normal human oral flora. Most streptococci are facultative anaerobes, and some are obligate anaerobes. Serologic grouping is based on antigenic differences in cell wall carbohydrates, in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. Streptococcus gordonii is a commensal member of the human oral flora. It initiates the formation of biofilms on tooth surfaces known as dental plaque, which is strongly associated with the development of dental cavities (caries) and gum disease. It is a frequent causative agent of bacterial endocarditis (inflammation of the membrane lining the heart) which often occurs as a result of oral trauma, allowing S. gordonii to invade the bloodstream and colonize the heart.

Subject: 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.
