Abstract

The taxonomic position of an actinomycete, strain HD321, isolated from an oil-producing well of Daqing oilfield, was clarified using a polyphasic taxonomic approach. The strain possessed cell-wall chemotype IV, MK-9(H) as the predominant menaquinone, relatively long-chain mycolic acids (52–62 carbon atoms) of the type, straight-chain saturated and monounsaturated fatty acids and tuberculostearic acid. The G+C content of the DNA was 66 mol%. 16S rDNA analyses as well as chemotaxonomic and physiological properties indicated that strain HD321 represents a novel species within the genus , for which the name sp. nov. is proposed; the type strain is HD321 (=AS 4.1730=DSM 44604).
