mutanolysin

Result Both mutanolysin and lysozyme could successfully lyse the wall of bifidobacterium and extract the plasmid from Bifidobacterium.

结果球孢链霉发酵液与酶均成功提取到质粒。

Method Bifidobacterium plasmid was extracted by mutanolysin from Streptomyces globisporus which could lyse the wall of bifidobacterium.The result was compared with that by lysozyme.

方法利用球孢链霉发酵产生的变来消化双歧杆细胞壁，提取质粒，并与商业化酶法比较。
