Abstract

An aerobic, Gram-stain-negative, rod-shaped, non-motile bacterium capable of degrading the polycyclic aromatic hydrocarbon pyrene was isolated from sediment of Pearl River and designated PrR001. 16S rRNA gene sequence analysis revealed that this strain was affiliated within the genus in the family of the class and showed great similarity with the type strain 20V17 (96.3 % similarity). The DNA G+C content of strain PrR001 was 68.3 mol%. The major cellular fatty acids comprised summed feature 8 (C 7/C 6), C cyclo 8, C 3OH, and C. The sole respiratory lipoquinone was ubiquinone-10. The main polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, an unidentified aminolipid, an unidentified aminophospholipid and three unidentified phospholipids. Based on physiological, chemotaxonomic and phylogenetic analysis, strain PrR001 is suggested as a novel species in the genus , for which the name sp. nov. is proposed. The type strain of is PrR001 (=CICC 24263=KCTC 62192).
