sp. nov., an actinobacterium isolated from soil Free

Abstract

A novel actinomycete, designated HM 537, was isolated from soil in Hamedan Province, Iran. Cell-wall hydrolysates of strain HM 537 contained -diaminopimelic acid, and whole-cell hydrolysates contained ribose, glucose, galactose, rhamnose and traces of mannose. The main phospholipids were diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol and an unknown phospholipid. MK-9(H), an unknown MK and MK-10(H) were the predominant menaquinones. The major fatty acids included iso-C, iso-C, iso-C G and 9(?)-methyl C. Strain HM 537 had the highest 16S rRNA gene sequence similarity to DSM 45457 (99.5 %) and DSM 45456 (99.0 %). DNA–DNA hybridization studies showed relatedness values of 13.8 ± 3.3 % with DSM 45457 and 16.3 ± 3.5 % with DSM 45456. Based on the results of phenotypic and genotypic studies, strain HM 537 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is HM 537 ( = DSM 45486 = UTMC 00537 = CCUG 63021).
