玉米浆粉预处理对粘质沙雷氏菌发酵产2-酮基-D-葡萄糖酸的影响
Effects of pretreatment with corn steep powder on the fermentation of 2-keto-D-gluconic acid by Serratia marcescens
摘要
Abstract
By comparing the effects of corn steep powder with different pretreatment methods on the production of 2-keto-D-gluconic acid by Serratia marcescens SD136,corn steep powder were compounded.The results showed that the optimum ratio of corn steep powder and enzymolysis corn steep was 3∶ 1,the yield of 2-keto-D-gluconic acid increased to (171.39 ± 4.5) g/L,the fermentation period shortened from 40 h to 37 h,and the sugar conversion rate reached 95.22％.The combination of corn steep powder and enzymolysis corn steep powder can improve the fermentation efficiency of Serratia marcescens SD136 and the production of 2-keto-D-glueonic acid.关键词
