title: Streptomyces graminilatus sp. nov., isolated from bamboo litter.
abstract: A Gram-stain-positive, novel actinobacterium, designated strain JL-6(T), was isolated from the litter of a bamboo (Sasa borealis) forest in Damyang, Korea. Strain JL-6(T) had white-grey, smooth, cylindrical spores that were borne in straight, long spore-chains. The novel strain grew aerobically at 15-28 °C (optimum, 28 °C), pH 4.0-8.0 (optimum, pH 5.5) and with 0-1.5% (w/v) NaCl. The cell-wall peptidoglycan contained ll-diaminopimelic acid, glutamic acid, alanine and glycine. The predominant menaquinones were MK-9(H6) and MK-9(H8). Whole-cell hydrolysates mainly contained glucose and ribose. Phosphatidylinositol and phosphatidylcholine were the diagnostic phospholipids. The G+C content of the genomic DNA was 72.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain JL-6(T) belonged to the genus Streptomyces with sequence similarities ranging from 97.3% to 98.3%. However, DNA-DNA hybridization between JL-6(T) and the closest related strain, Streptomyces turgidiscabies, ATCC 700248(T) and other closely related species in the genus Streptomyces showed <50% relatedness. Based on these observations, strain JL-6(T) is proposed to represent a novel species of the genus Streptomyces, for which the name Streptomyces graminilatus sp. nov. is proposed. The type strain is JL-6(T) ( = KACC 16470(T) = NBRC 108882(T)).
