title: [Taxonomic studies of two Streptomycete strains AS 4.693 and AS 4.702].
abstract: The "setae group" of the genus Streptomyces was originally the genus Kitasatosporia (Omura, 1982). On the basis of 16s rRNA analysis, Wellington(1992) proposed to reduce Kitasatosporia to synonymy with Streptomyces as a species group--"setae group". Two Streptomyces strains, AS 4.693 and AS 4.702(deposited in CCCCM) were examined by using morphological, chemical and nucleic acid ribtyping methods. It was revealed that these two strains have similarity to the type strain Streptomyces setae JCM3304T, and they share 100% DNA homology with JCM 3304T. Therefore, we propose that the strain AS 4.693 be transferred to the "setae group" of genus Streptomyces as Streptomyces setae subsp. irregularis nov. and the strain AS 4.702 as Streptomyces setae subsp. flexuofradiae nov.
