sp. nov., isolated from surface seawater Free

Abstract

A taxonomic study was carried out on strain DLFJ1-1, which was isolated from an oil-degrading bacterial consortium, enriched by the surface seawater from around the Dalian Peninsula. The isolate was Gram-reaction-negative, oxidase- and catalase-positive, short-rod-shaped and non-motile. Growth was observed at salinities from 0.5 to 15 % and at temperatures from 4 to 37 °C; the strain was unable to degrade gelatin or to reduce nitrate. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain DLFJ1-1 belonged to the genus , with the highest sequence similarity (96.4 %) to TL 2, while the similarities to other species examined were all below 95.0 %. The principal fatty acids were Cω8 cyclo and summed feature 8 (Cω7/ω6). The major quinone of strain DLFJ1-1 was Q10. The major polar lipids of strain DLFJ1-1 were phosphatidylethanolamine and phosphatidylglycerol. The G+C content of the chromosomal DNA was 62.5 mol%. The combined genotypic and phenotypic data show that strain DLFJ1-1 represents a novel species of the genus , for which the name sp. nov. is proposed, with the type strain DLFJ1-1 ( = CGMCC 1.12325 = LMG 27290 = MCCC 1A03957). An emended description of the genus is also proposed.
