A novel Gram-negative, orange-pigmented, slightly halophilic, rod-shaped bacterium, strain T30(T), was isolated from sediment from the South China Sea. Phylogenetic analysis showed that strain T30(T) was a member of the genus Erythrobacter, sharing highest 16S rRNA gene sequence similarities with Erythrobacter aquimaris JCM 12189(T) (99.5%) and Erythrobacter vulgaris DSM 17792(T) (99.0%). Levels of DNA DNA relatedness between strain T30(T) and closely related strains of Erythrobacter species ranged from 14.5 to 56.9%. The isolate lacked bacteriochlorophyll a and contained ubiquinone-10 as the predominant respiratory lipoquinone. The major fatty acids of this strain were C(18:1)omega 7C (38.2%) and C(16:1)omega 7c/C(16:1)omega 6c (17.4%). The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine and phosphatidylglycerol. The DNA G+C content of strain T30(T) was 59.5 mol%. On the basis of phenotypic and phylogenetic data, a novel species, Erythrobacter nanhaisediminis sp. nov., is proposed; the type strain is T30(T) (=CGMCC 1.7715(T)=JCM 16125(T)).
