【摘要】 对糖化酶在工业生产中影响酶活力的几个主要因素进行了试验研究，获得培养基最适浓度为２０．２５％，准确控制发酵培养基的标准体积、浓度及其适宜通风量（前期控制在１：０．４０～０．４７，中期为１：０．５５～０．６５，后期为１：０．５～０．５５）是糖化酶生产中稳产高产的关键技术措施。结果表明：采取该措施提高酶活力４７．３２％，经济效益显著。更多还原

【Abstract】 ABSTRACT Through experiment and research on several key factors affacting the enzymatic activity ofGlucoamylase in industry，we discovery that the most appropriate concentration of the mediumis 20．25％，and that controlling strictly standard volume and concentration of fermentation me-dium and appropriate ventilation（early stage 1：0．40—0．47．middle stage 1：0．55—0．65，laterstage 1：0．50—0．55．）is the key technological measures to ensure high and stable yields ofGlucoamylase．The testing results show that adopting the nieasures can increase the enzymaticactivity by 47．32％ with notable economical gainings.
