    • The process of this invention is directed to isolating or otherwise obtaining an olefinic macrolide producing microorganism which microorganism does not contain epoxidase enzyme activity. This invention also relates to a process for preparing said olefinic macrolide by fermenting a mutant microorganism lacking epoxidase activity, designated rosX herein, which mutant is obtained from the wild-type microorganism. This invention also relates to a rosX mutant of Micromonospora rosaria, and to any microorganism having the identifying characteristics thereof, said mutant also designated ATCC 55709. This invention also relates to a process for preparing repromicin, the compound of formula (II), ##STR1## by mutating a wild-type microorganism capable of producing rosamicin to produce a mutant microorganism lacking epoxidase activity such that repromicin is produced by said mutant microorganism.
    • 本发明的方法涉及分离或以其它方式获得微生物不含有环氧酶酶活性的烯烃大环内酯生产微生物。 本发明还涉及一种通过发酵缺少环氧酶活性的突变体微生物制备所述烯烃大环内酯的方法,本文命名为rosX,该突变体获自野生型微生物。 本发明还涉及Roson突变体和具有鉴定特征的任何微生物,所述突变体也称为ATCC 55709.本发明还涉及一种制备repromicin,式(II)化合物,IMAGE (II)通过突变能够产生罗素霉素的野生型微生物来产生缺少环氧酶活性的突变微生物,使得所述突变微生物产生repromicin。
