乳酸链球菌素产生菌的筛选初报

A primary report on the screening of nisin-producing strain

采用一种简单、高效的定向筛选乳酸链球菌素产生菌的方法,筛选到了3株乳酸乳球菌,并对其中的M9菌株的形态、生理生化特性及遗传稳定性进行了初步研究。

A simple and efficient method to directionally screen nisin-producing strain was used successfully to obtain three strains of Lactococ cus lactis. The morphology, physiology, biochemistry and genetic stability of strain M9 was investigated primarily.
