Polaramonas napthalenivorans CJ2
Description and significance
P. naphthalenivorans is an aquatic gram-negative, non-spore forming, non-motile coccus that is capable of growth with naphthalene as its sole carbon and energy source. (2)
The genus Polaromonas was proposed in 1996 and contained only one species, P. vacuolata, until 2004 when P. naphthalenivorans was discovered. (3) Strain CJ2 was isolated from coal-tar-contaminated freshwater sediment in South Glens Falls, New York, USA. (1) It was discovered using stable isotope probing (SIP), a technique that enabled researchers to follow the flow of labeled carbon atoms from naphthalene to the DNA of naturally occurring microbial populations in the environment such as P. naphthalenivorans. (4)
It is important to have the genome of P. naphthalenivorans sequenced because of its ability to efficiently remove naphthalene from solution. Naphthalene is a polycyclic aromatic hydrocarbon (PAH) that can cause contamination of soil, water or sediment and can be toxic and/or carcinogenic. (2)
