Abstract

A novel endophytic actinomycete, strain GMKU 931, was isolated from the root of a wattle tree, A. Cunn. ex Benth., collected at Kasetsart University, Bangkok, Thailand. Strain GMKU 931 produced short spiral chains of smooth-surfaced spores on the aerial mycelium. Lysine and -diaminopimelic acid were present in the cell-wall peptidoglycan. Whole-cell hydrolysates contained galactose, madurose and mannose. The predominant menaquinones were MK-9(H) and MK-9(H). The major fatty acids were iso-C and iso-C. The major phospholipids were phosphatidylinositol and phosphatidylglycerol. A phylogenetic analysis based on 16S rRNA gene sequences suggested that strain GMKU 931 forms a distinct phyletic line within the recently proposed genus . The significant differences in phenotypic and genotypic data indicate that strain GMKU 931 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is GMKU 931 (=BCC 28622 =NBRC 104354 =NRRL B-24610).
