Nybomycin-producing Streptomyces isolated from carpenter ant Camponotus vagus.

A novel strain of Actinomycetes was isolated from the body of an ant (Camponotus vagus Scopoli) and its genetic and morphological properties were characterized. The 16S rDNA gene sequence analysis of the isolate revealed its high phylogenetic relationship with type strains of Streptomyces violaceochromogenes NBRC 13100. As a result of antimicrobial activity assessment, it was found that the fermentation broth of the isolated strain both inhibited the growth and induced the SOS response in E.
