title: Streptomyces andamanensis sp. nov., isolated from soil.
abstract: A novel actinomycete, strain KC-112T, was isolated from soil collected from Similan Islands, Phang-Nga Province, Thailand. The strain exhibited morphological and chemotaxonomic characteristics consistent with those of members of the genus Streptomyces. The formation of smooth spiral spore chains was observed on aerial mycelia. ll-Diaminopimelic acid was detected in whole-cell hydrolysates, but no diagnostic sugars were detected and the strain lacked mycolic acids. The N-acyl type of muramic acid was acetyl. The major menaquinones were MK-9(H8), MK-9(H6) and MK-9(H2). The predominant cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and C16 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, an unknown phospholipid, an unknown aminolipid, unknown lipids and an unknown glycolipid. The DNA G+C content was 73 mol%. On the basis of 16S rRNA gene sequence analysis, strain KC-112T was closely related to Streptomyces fumanus NBRC 13042T (98.8 % 16S rRNA gene sequence similarity), Streptomyces anandii NBRC 13438T (98.8 %) and Streptomyces capillispiralis NBRC 14222T (98.8 %). DNA-DNA relatedness values among strain KC-112T and type strains of closely related species were lower than 70 %. On the basis of evidence from this taxonomic study using a polyphasic approach, strain KC-112T represents a novel species of the genus Streptomyces, namely Streptomyces andamanensis sp. nov. The type strain is KC-112T ( = KCTC 29502T = NBRC 110085T = PCU 347T = TISTR 2401T).
