  • Strain No.77-AG-567 showed antifungal activity against Pyricularia oryzas and Sphaerotheca fuliginea. In the process of purification of active component this strain was found to produce blasticidin S together with another antibiotic. This compound was identified as being acetoxycyc-heximide, also referred to as E-73, by UV and $^1$H NMR spectral data. Identification of this strain led us to conclude that strain No.77-AG-567 is most probably be Streptomyces atratus. It showed different characteristics from S. atbutus, so far known to produce both blasticidin S and acetoxycycloheximide. Particularly worthy of note was the difference in spore surface. In addition, acetoxycycloheximide has been known to have activity only against yeast and tumor cells but we found that it also has activity against Pyricularia oryzae and Sphasrotheca fuliginea.
