Abstract: Two novel actinomycetes, strains TA4-1T and TA4-8T, were isolated from the South-East Asian stingless bee (Tetragonilla collina Smith 1857), collected from Chiang Mai Province, Thailand. The morphological and chemotaxonomic properties of strains TA4-1T and TA4-8T were consistent with the genus Streptomyces, i.e. the formation of aerial mycelia bearing spiral spore chains, the presence of the LL-isomer of diaminopimelic acid in cell walls, iso- and anteiso-branched fatty acids with carbon chain lengths 14-17 atoms as the major fatty acids and MK-9(H8) as the predominant menaquinone plus minor amounts of MK-9(H6) and MK-9(H10). Analysis of 16S rRNA gene sequences showed that strains TA4-1T and TA4-8T exhibited 98.8 and 98.1 % sequence similarity, respectively, with Streptomyces chromofuscus NRRL B-12175Tand 98.9 % sequence similarity with each other. This study suggested that strains TA4-1T and TA4-8T were distinct from previously described species of the genus Streptomyces. In addition, the low degrees of DNA-DNA relatedness between the isolates and S. chromofuscus JCM 4354Twarranted assigning strains TA4-1T and TA4-8T to two novel species. The names Streptomyces chiangmaiensis sp. nov. (type strain TA4-1T = JCM 16577T = TISTR 1981T) and Streptomyces lannensis sp. nov. (type strain TA4-8T = JCM 16578T = TISTR 1982T) are proposed. The species names indicate the geographical locations where the stingless bees reside. © 2013 IUMS.
