A taxonomic study was carried out on strain W3-3AT, which was isolated from a Pyrene-degrading consortium, enriched from the sediment of the Pacific Ocean. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain W3-3AT belonged to the genus Bowmanella, with highest sequence similarity of 99.0% to Bowmanella denitrificans BD1T, while the others were all below 93%. Both nucleotide sequence similarity of gyrB and rpoD gene between strain W3-3AT and B. denitrificans BD1T were 81.1%. But the protein sequence similarity of gyrB and rpoD gene between strain W3-3AT and B. denitrificans BD1T were 96.1% and 91.0%, respectively. Phylogenetic tree based on these housekeeping genes showed that strain W3-3AT and B. denitrificans BD1T formed a distinct lineage in the Gammaproteobacteria. DNA-DNA hybridization values between strain W3-3AT and B. denitrificans BD1T was 43%. The Rep-PCR fingerprint also differentiated strain W3-3AT from B. denitrificans BD1T. The G+C content of the chromosomal DNA was 49 mol%. The combined genotypic and phenotypic data show that strain W3-3AT represents a novel species of the genus Bowmanella, for which the name Bowmanella pacifica sp. nov. is proposed, with the type strain W3-3AT (=CGMCC 1.7086T =LMG 24568T=MCCC 1A01018T).
