Agromyces flavus sp. nov., an actinomycete isolated from soil.

A gram-positive, non-motile strain, designated CPCC 202695(T), was isolated from a soil sample collected from the Qinghai-Tibet plateau, north-west China. Strain CPCC 202695(T) contained rhamnose, glucose and galactose in the cell wall as diagnostic sugars and 2,4-diaminobutyric acid, alanine, glutamic acid and glycine in the peptidoglycan. The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol and two unknown glycolipids. MK-12 was the predominant menaquinone and anteiso-C(15 : 0) (34.2 %), iso-C(15 : 0) (19.8 %), iso-C(16 : 0) (12.7 %) and anteiso-C(17 : 0) (11.1 %) were the major fatty acids. 16S rRNA gene sequence similarities (94.2-97.1 %) between the isolate and the type strains of recognized species of the genus Agromyces indicated that strain CPCC 202695(T) was a member of the genus Agromyces. DNA-DNA relatedness clearly separated strain CPCC 202695(T) from its closest relatives. The phenotypic and genotypic data demonstrated that strain CPCC 202695(T) represents a novel species of the genus Agromyces, for which the name Agromyces flavus sp. nov. is proposed. The type strain is CPCC 202695(T) ( = KCTC 19578(T)  = CCM 7623(T)).
