摘要
Abstract
The influence of carbon/nitrogen ratio and carbon,nitrogen sources upon fermentation in the production of BAA mesophilic α-amyase was studied.Results showed that fermentation vigor breaked through 900U/mL and averages in 832U/mL.Before comparing optimized the 600U/mL averagely promoting fermentation unit by 38,on the condition that 40% maize meal-60% corn starch was used as carbon source,newly standardized nitrogen source-cottonseed cake powder was used as the nitrogen source,the carbon nitrogen source mass ratio was 14:5,import fermentation defoamer addition was 1/10000,using feeding process and under optimal condition.关键词
