【摘要】 用含有10000单位/毫升洁霉素的高氏一号琼脂培养基制成洁霉素浓度梯度培养皿,然后在上述梯度培养皿上分离诱变处理后的变异菌株。实验证明,从洁霉素浓度梯度培养皿分离得到的菌株,它的洁霉素产生能力,比用常规方法从高氏1号琼脂平板得到的菌株的洁霉素产生能力高6％左右。更多还原

【Abstract】 This paper presents a gradient plate technique for selection of Lincomycin producing strains. The gradient plate contained 10,000u/ml Lincomycin in Gause No. 1 me-dium. It was proved that the strains selected from gradient plate produced more Lincomycin (about 6%) than that one from normal plate.更多还原
