Abstract

A novel actinomycete strain, Bv016, belonging to the genus , was isolated from the bark of tree, Linn., collected in Thailand. The taxonomic position of the strain was characterized by using a polyphasic approach. -Diaminopimelic acid, glucose, mannose, ribose and galactose were detected in its whole-cell hydrolysates. The -acyl type of muramic acid was acetyl. The strain contained anteiso-C , iso-C , iso-C and iso-C as the major fatty acids and MK-9(H), MK-9(H) and MK-9(H) as the major menaquinones. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannoside. The strain was closely related to JCM 4041 (98.4 %), JCM 10116 (98.4 %) and JCM 4408 (98.2 %). The draft genome of Bv016 was 6.74 Mb with 5949 coding sequences with an average G+C content of 71.7 mol%. The ANIb and ANIm values of strain Bv016 were 94.1 and 95.2 %, respectively, and the digital DNA–DNA hybridization value was 60.6 % in comparison with the draft genome of JCM 4765. The results of the taxonomic analysis suggested that strain Bv016 represented a novel species of the genus for which the name sp. nov. is proposed. The type strain is Bv016 (=JCM 33208=TISTR 2645).
