Query: NC_008781:330919 Polaromonas naphthalenivorans CJ2, complete genome Lineage: Polaromonas naphthalenivorans; Polaromonas; Comamonadaceae; Burkholderiales; Proteobacteria; Bacteria General Information: Naphthalene-degrading bacterium. Polaromonas naphthalenivorans was isolated from naphthalene-contaminated, freshwater sediment. This organism is capable of aerobic degradation of naphthalene at temperatures of less than 20 degrees C. Naphthalene is a polycyclic aromatic hydrocarbon (PAH). PAHs can be toxic and/or carcinogenic, therefore PAH contamination is of considerable concern.

General Information: This organism was isolated from a calcereous (chalky) rock in Switzerland. Photosynthetic bacterium. This organism is an obligate photoautotroph that lacks thylakoid membranes and probably has its photosynthetic machinery in the cytoplasmic membrane with various components exposed to the periplasm whereas in other cyanobacteria the components are situated in the thylakoid membrane and are exposed to the cytoplasm. This unusual arrangement may be due to the lack of various fatty acids that are found in the thylakoid membrane in other cyanobacteria. It has been predicted that this organism was one of the earliest to diverge from the cyanobacterial line.
