mutanolysin

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

结果球孢链霉菌发酵液与菌酶均成功提取到质粒。

2.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.

方法利用球孢链霉菌发酵变菌化双歧杆菌细胞壁，提取质粒，并与商业化菌酶法比较。
