Abstract

A novel Gram-negative, orange-pigmented, slightly halophilic, rod-shaped bacterium, strain T30, was isolated from sediment from the South China Sea. Phylogenetic analysis showed that strain T30 was a member of the genus , sharing highest 16S rRNA gene sequence similarities with JCM 12189 (99.5 %) and DSM 17792 (99.0 %). Levels of DNA–DNA relatedness between strain T30 and closely related strains of species ranged from 14.5 to 56.9 %.The isolate lacked bacteriochlorophyll and contained ubiquinone-10 as the predominant respiratory lipoquinone. The major fatty acids of this strain were C 7 (38.2 %) and C 7 /C 6 (17.4 %). The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine and phosphatidylglycerol. The DNA G+C content of strain T30 was 59.5 mol%. On the basis of phenotypic and phylogenetic data, a novel species, sp. nov., is proposed; the type strain is T30 (=CGMCC 1.7715=JCM 16125).
