摘要: Two novel actinomycetes, designated strains 2C-SSA16(2)(T) and 1C-GS8(T), were isolated from the cuticle of Camponotus japonicus Mayr, collected from Northeast Agricultural University, Heilongjiang Province, north China. Both of them contained genes (involved in antibiotics biosynthesis) of the ketosynthase (KS) and methyl malonyl transferase domains (PKS-I) and the adenylation domain (NRPS). A polyphasic study was carried out to establish the taxonomic positions of these strains. The 16S rRNA gene sequence analysis showed that the two novel isolates 2C-SSA16(2)(T) and 1C-GS(T) exhibited 98.8% similarity with each other and that they are most closely related to Streptomyces umbrinus JCM-452(T) (99.0, 98.6%), Streptomyces ederensis JCM 495(T) (98.9, 98.7%), Streptomyces aurantiacus JCM 445(T) (98.6, 98.2%), Streptomyces glomeroaurantiacus JCM 4677(T) (98.6, 98.1%), Streptomyces tauricus JCM4837(T) (98.2, 98.0%) and Streptomyces phaeochromogenes JCM 4070(T) (98.2, 99.2%). The corresponding phylogenetic analysis based on partial gyrB gene sequences showed that strains 2C-SSA16(2)(T) and 1C-GS8(T) formed a cluster with the above-mentioned strains. The DNA-DNA hybridization data and phenotypic characteristics indicated that strains 2C-SSA16(2)(T) and 1C-GS8(T) could be readily distinguished from each other and their closest phylogenetic relatives. Therefore, these two strains are suggested to represent two novel species of the genus Streptomyces, for which the names Streptomyces camponoti sp. nov. and Streptomyces cuticulae sp. nov. are proposed. The type strains are 2C-SSA16(2 T (=CGMCC 4.7276(T) =DSM-100522(T)) and 1C-GS8(T) (=CGMCC 4.7348=DSM-03127(T)), respectively.
