sp. nov., a polycyclic aromatic hydrocarbons-degrading and acylhomoserine-lactone-producing bacterium isolated from marine biofilm, and emended description of the genus Free

Abstract

A polycyclic aromatic hydrocarbons-degrading and acylhomoserine-lactone-producing marine bacterium, designated strain PQ-2, was isolated from marine biofilm collected from a boat shell at a harbour of Zhoushan island in Zhejiang Province, PR China. Strain PQ-2 is Gram-stain-negative, yellow-pigmented, non-motile and short rod-shaped. Optimal growth of strain PQ-2 was observed at 32 °C, at pH 7.0 and in 2 % (w/v) NaCl. The 16S rRNA gene sequence of strain PQ-2 showed highest similarity to E4A9 (96.3 %) followed by MUSC 273 (95.6 %) and H32 (95.6 %). Phylogenetic analysis with all species of the family with validly published names revealed that strain PQ-2 formed a phyletic line with E4A9 that was distinct from other members of the family . The sole respiratory quinone was ubiquinone 10 (Q-10). The predominant fatty acids were Cω7, Cω6 and summed feature 3 (Cω7 and/or iso-C 2-OH). The genomic DNA G+C content was 61.7 mol%. In the polar lipid profile, phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol, one unidentified phospholipid and one sphingoglycolipid were the major compounds; and another sphingoglycolipid was present in a minor amount. Based on the genotypic and phenotypic data, strain PQ-2 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is PQ-2 ( = CGMCC 1.12805 = NBRC 110381). In addition, emended descriptions for the genus and the species are given.
