Abstract

A novel marine actinobacterium, strain SCSIO 58843, was isolated from the sediment sample collected from the South China Sea. Strain SCSIO 58843 was Gram-stain-positive, aerobic and rod shaped. The whole-cell hydrolysis of amino acids contained -DAP, alanine, glutamic acid, glycine and aspartic acid. The main menaquinone was MK-9(H). The major fatty acids were C ω and C. The major phospholipids were diphosphatidylglycerol (DPG), phosphatidylinositol (PI), phospatidylcholine (PC) and phosphatidylinositolmannoside (PIM). The G+C content of the genomic DNA was 72.5 %. Phylogenetic analysis of the 16S rRNA gene sequences showed that strain SCSIO 58843 formed a new lineage in the family and had the highest similarity of 93.8 % with DSM 19957. Strain SCSIO 58843 can be distinguished from these known genera in the family by polyphasic data analyses, and represents a novel genus and novel species, for which gen. nov., sp. nov is proposed with the type strain SCSIO 58843(=KCTC 49408=CGMCC 1.17503).
