Complete Genome Sequence of the Polycyclic Aromatic Hydrocarbon-Degrading Bacterium

Alteromonas sp. strain SN2, able to metabolize polycyclic aromatic hydrocarbons, was isolated from a crude oil-contaminated sea-tidal flat. Here we report the complete 4.97-Mb genome sequence and annotation of strain SN2. These will advance the understanding of strain SN2’s adaptation to the sea-tidal flat ecosystem and its pollutant metabolic versatility. Members of the genus Alteromonas are increasingly recog-nized as globally distributed heterotrophic marine bacteria, having a copiotrophic way of life as an r-strategist, i.e., they can grow rapidly when a new carbon source, such as crude oil, is released into marine habitats (6, 10). Thus, it may be antici-pated that Alteromonas species are functionally important in the recovery of marine habitats from pollution. Alteromonas sp. strain SN2 was isolated from a sea-tidal flat, and it was shown to be responsible for the in situ degradation of polycyclic aro-matic hydrocarbons (PAHs) in crude oil-contaminated marine sediment (H.
