Complete genome sequence of a psychrotolerant and piezotolerant bacterium Parasedimentitalea marina W43T, isolated from deep sea water of the New Britain trench.

Parasedimentitalea marina W43T is a novel psychrotolerant and piezotolerant Rhodobacteraceae bacterium isolated from deep-sea water (4000 m) of the New Britain Trench. Here we present the first complete genome sequence of the bacterial genus Parasedimentitalea, which contains a circular chromosome and four plasmids. The 5,080,916 bp long genome exhibits a G + C content of 55.9 mol% and contains 5090 protein-coding and 97 RNA genes. Genomic analysis revealed abundant clues on bacterial cold and high-pressure adaptation and deep-sea lifestyle. The genome is consistent with a heterotrophic, psychrotolerant and piezotolerant lifestyle of the deep-sea environment.
