摘要
苏云金芽孢杆菌经紫外线诱变后,通过镜检斜面培养、摇瓶培养伴孢晶体形态两步初筛,再经过摇瓶发酵复筛,提高了正突变的被选中概率,提高了菌种选育的效率。
After the strain of Bacillus thuringiensis be treated with UV, the positive mutation can be selected mostly through two step original selection which is observing the characteristics of insecticide crystal obtained from slant and liquid cultivations. Thus the efficiency of selection is enhanced.
