The present invention teaches a new antibiotic nanaomycin E represented by the formula: ##STR1## Nanaomycin E is active against Gram-positive bacteria, Trichophyton and Mycoplasma and may be used as antibacterial and therapeutic agents for humans and animals. Nanaomycin E is also a useful starting material for the preparation of nanaomycin A which latter nanaomycin has the highest activity among the various nanaomycin-type compounds. Nanaomycin E is produced by fermentation of a microorganism belonging to the genus Streptomyces and capable of producing nanaomycin E, especially Streptomyces rosa variant notoensis (FERM-P 2209; ATCC 31135) and recovering the same from the fermented liquor.
本发明教授了一种新的抗生素nanaomycin E,其化学式为:##STR1## Nanaomycin E对革兰氏阳性菌、毛癣菌和支原体具有活性,并可用作人类和动物的抗菌和治疗剂。Nanaomycin E也是制备nanaomycin A的有用起始材料,后者是各种nanaomycin型化合物中活性最高的一种。Nanaomycin E是通过发酵属于链霉菌属的微生物并能够产生nanaomycin E的菌株,特别是Streptomyces rosa variant notoensis (FERM-P 2209; ATCC 31135),并从发酵液中回收而得到的。
