Title: Compound Mutagenesis of HNO_2 and UV of Protoplast on Screening of Enzyme-producing Strain
Abstract: Objective:A stable,high-yield neutral proteinase-producing strain can be screened.Methods:Compound mutagenesis of UV and HNO_2 on protoplast from Bacillus subtiIis UV_(11) was launched and protoplast was prepared at its optimal formation and regeneration conditions.Re- suits:A mutant strain Bacillus subtilis UN_(19) was obtained and its neutral proteinase-producing capacity was improved from 378.97U/ml to 3965.84U/ml.Condusion:The method of compound mutagenesis of HNO_2 and UV of protoplast for screening of high producing strain was con- firmed as a good way.
