Abstract

A novel Gram-stain-positive, irregularly rod-shaped actinomycete, designated strain 002-2, was isolated from sand beach sediment collected from the Taean seashore, Republic of Korea. Cells were aerobic, oxidase-negative and catalase-positive. Colonies of cells were bright yellow, circular, smooth and convex. The diagnostic diamino acid in the cell wall was -diaminopimelic acid. The predominant menaquinone was MK-8(H). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unknown phospholipid and two unknown amino phospholipids. The major fatty acids were iso-C and Cω8. The DNA G+C content was 68.8 mol%. 16S rRNA gene sequence analysis revealed that strain 002-2 belongs to the family and formed a cluster with Sco-A25 (98.1 % sequence similarity) and NCIMB 12834 (97.6 %). On the basis of the phenotypic and phylogenetic data, strain 002-2 (=KCTC 39838=DSM 103718) is considered to represent a novel species of the genus , for which the name sp. nov. is proposed.
