摘要
以黑曲霉（ Ａｓｐ ｅｒｇｉｌｌａｓ ｎｉｇｅｒ）为出发菌株，经硫酸二乙酯、亚硝基胍、紫外线多次诱变，使糖化酶的活力比原菌株提高。
The Aspergillus Niger mutant strain St\|9308 h as been selected by treating Aspergillus Niger with DES,NTG,UV.The activity of g lucoamylases from fermentation of mutant strain St\|9308 was heightened as compa red with the original and the conditions for the production of ampicillin glucoa mylases have also been investigated.
