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菌酶均成功提取到质粒。

When the denatured reduced egg white lysozymes were renatured by dilution method, an observable amount of aggregate precipitate could be immediately formed.

当用复性稀释复性原服变性蛋白菌酶时，会迅速产生可观量的。

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.

法利用球孢链霉菌发酵产生的变菌素来消化双歧杆菌细胞壁，提取质粒，并商业化菌酶法比较。
