摘要: During a screening for novel and biotechnologically useful actinobacteria in insects, a kanchanamycin-producing actinomycete with antifungal activity, designated strain 3H-HV17(2)(T), was isolated from the head of an ant (Lasius fuliginosus L.) and characterized using a polyphasic approach. 16S rRNA gene sequence similarity studies showed that strain 3H-HV17 (2) T belongs to the genus Streptomyces with the highest sequence similarities to Streptomyces spectabilis NBRC 13424(T) (98.90 %, with which it phylogenetically clustered, Streptomyces alboflavus NRRL B-2373(T) (98.65 %) and Streptomyces flavofungini NBRC 13371(T) (98.36 %). Phylogenetic analysis based on the gyrB gene also supported the close relationship of these strains. The morphological and chemotaxonomic properties of the strain are also consistent with those members of the genus Streptomyces. A combination of DNA-DNA hybridization experiments and phenotypic tests were carried out between strain 3H-HV17(2)(T) and its phylogenetically closely related strains, which further clarified their relatedness and demonstrated that strain 3H-HV17(2)(T) could be distinguished from these strains. Therefore, strain 3H-HV17(2)(T) is concluded to represent a novel species of the genus Streptomyces, for which the name Streptomyces lasiicapitis sp. nov. is proposed. The type strain is 3H-HV17(2)(T) (=CGMCC 4.7349(T)=DSM 103124(T)).
