Study on the Conditions of Glucoamylase Production of the Rhizopus Oryzae in Luzhou-flavor Daqu by Solid State Fermentation
摘要
Abstract
The conditions of glucoamylase production of the Rhizopus oryzae in Luzhou - flavor Daqu by solid state fer- mentation are studied. By single factor experiment and saccharifying enzymic activityas as an assessing index, the influence on saccharifying enzymic aetivityas of the water content in culture medium, the culture time, the culture temperature are stud- ied. According to the Box-Benhnken design, the conditions of glucoamylase production of the Rhizopus oryzae are optimized by solid state fermentation. The results show that the optimum conditions of glucoamylase production of the Rhizopus oryzae in Luzhou-flavor Daqu by solid state fermentation are the culture temperature 29℃, the water content in culture medium 53%, culture time 164h, glucoamylase activity was 2 194.44U/g.关键词
