Abstract
Colwellia sp. NB097-1, isolated from a marine sediment sample from the Bering Sea, is a psychrophilic bacterium whose optimal and maximal growth temperatures were 13 and 25 °C, respectively. Here, we present the complete genome of Colwellia sp. NB097-1, which was 4,661,274 bp in length with a GC content of 38.5%. The genome provided evidence for the potential genetic basis for its adaptation to a cold environment, such as producing compatible solutes and cold-shock proteins, increasing membrane fluidity and synthesizing glycogen. Some cold-adaptive proteases were also detected in the genome of Colwellia sp. NB097-1. Protease activity analysis further showed that extracellular proteases of Colwellia sp. NB097-1 remained active at low temperatures. The complete genome sequence may be helpful to reveal how this strain survives at low temperature and to find cold-adaptive proteases that may be useful to industry.
