| titleOfInvention | A kind of method of magnetic field mutagenesis Bifidobacterium Bifidum high-yield thermostable beta galactosidase |
| abstract | The invention discloses a kind of methods of magnetic field mutagenesis Bifidobacterium Bifidum high-yield thermostable beta galactosidase, are related to bioengineering field.The present invention includes the following steps that pressure regulator, ammeter and coil group are sequentially connected electrically by step 1, and accesses in circuit and constitute a mutagenesis magnetic field, several mutagenesis magnetic fields is then constructed to carry out magnetic field mutagenesis to Bifidobacterium Bifidum；The liquid fermentation bottle for being contained with quantitative Bifidobacterium Bifidum is placed in the coil group in several mutagenesis magnetic fields by step 2；The voltage of several pressure regulators is sequentially increased by step 3, and records the size of current in coil group by ammeter；Liquid fermentation bottle is set to stand 0.5~5h in coil group.The present invention carries out Mutagenesis to Bifidobacterium Bifidum by magnetic field, and high-yield thermostable beta galactosidase is then obtained by culture, high temperature bath and Enzyme assay, improves the production efficiency of high-yield thermostable beta galactosidase. |
