Abstract

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.

77-AG-567 균주는 Pyricularia oryzae와 Sphasrotheca fuliginea에 대한 항균활성을 나타냈다. 활성 물질을 정제해 가는 과정에서 이 균주는 blasticidin S와 또 다른 항생물질을 동시에 생산한다는 사실을 알았다. 이 화합물은 UV 및 $^1$H NMR 스펙트럼에 의해 E-73이라고도 일컬어지는 acetoxycycloheximide로 밝혀졌다. 균주를 동정해본 결과 77-AG-567균주는 Streptomyces atbutus로 판단되며 지금까지 blasticidin S와 acetoxycycloheximide를 동시에 생산하는 것으로 알려져 온 S. albulus와는 다른 특성을 나타냈다. 특히 주목할만한 차이점은 포자의 표면이였다. 또한 acetoxycycloheximide는 지금까지 효모와 종양세포에만 생리활성을 나타내는 것으로 알려져 왔으나 본 실험결과 Pyricularia oryzae와 Sphasrotheca fuliginea에도 항균활성을 가진다는 사실을 알았다.
