Abstract

An actinomycete, strain FXJ6.011, was isolated from a cup-shaped sponge collected at Dachan reef, Yangpu in the South China Sea. The strain had morphological characteristics of members of the family . Phylogenetic analysis of the 16S rRNA gene sequence of strain FXJ6.011 indicated the highest similarity (98.7 %) to JCM 12357, JCM 12873 and JCM 3327. Analysis of the gene sequence also showed that strain FXJ6.011 should be assigned to the genus . It contained -diaminopimelic acid as the major cell-wall diamino acid and MK-10(H) as predominant menaquinone. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidyl mannosides and phosphatidylinositol dimannoside. The major cellular fatty acids were iso-C, Cω8 and C. Physiological and biochemical data and low DNA–DNA relatedness values enabled the strain to be differentiated from members of closely related species. Based on phenotypic and genotypic data, strain FXJ6.011 represents a novel species, for which the name sp. nov. is proposed; the type strain is FXJ6.011 ( = CGMCC 4.5736 = NBRC 107727).
