摘要
利用微生物菌种（如绿僵菌Ｍｅｔａｒｈｉｚｉｕｍｓｐ）产生的１１α－羟化酶，催化甾体底物１６α，１７α－环氧黄体酮（１６α，１７α－ｅｐｏｘｙ－４－ｐｒｅｇｎｅｎｅ－３，２０－ｄｉｏｎｅ）羟化转化为产物１１α－羟基－１６α，１７α－环氧黄体酮，是当前甾...
The effect of addition of growth regulator into the microbial catalytic transformation system of steroid was investigated. It was shown that the proper concentration of growth regulator is 0.025%. Addition of proper quantity of growth regulator greatly enhanced the growth yield and the catalytic transformation activity of mold, when steroid substrate was added after 42 h of cultivation. This effect may be accounted for the ability of the growth regulator spreading itself into the cells in the nonionic form.
