Query: NC_008260:2340824 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_015713:2453409 Simkania negevensis Z chromosome gsn.131, complete genome
Lineage: Simkania negevensis; Simkania; Simkaniaceae; Chlamydiales; Chlamydiae; Bacteria
General Information: This bacterium is named after Simona Kahane who discovered the organism as a contaminant in cell cultures at Ber Sheva, in the Negev Desert, Israel, in 1993. Simkania negevensis is a member of the order Chlamydiales and can reside intracellularly and has a slow prolonged developmental cycle. It has a wide geographical and environmental distribution and is associated with pneumonia, bronchiolitis and chronic obstructive pulmonary disease, furthermore, it is completely resistant to penicillin and to bacitracin. The natural hosts of Simkania negevensis bacteria might be amoebae.
