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.

当用复性液稀释复性原服变性蛋白时，会迅速产生可观淀。

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.
