摘要
研究了黑曲霉细胞的生长及其葡萄糖氧化酶、过氧化氢酶的生物合成．ＣａＣＯ３是２种酶的产酶诱导因子，其产酶模式都是延续合成型，最大比生长速度μｍａｘ、菌体得率Ｙ（Ｘ／Ｓ）、葡萄糖氧化酶及过氧化氢酶合成得率Ｙ（ＧＯＤ／Ｓ）、Ｙ（ＣＡＴ／Ｓ）分别为０．０９７ｈ－１、０．０７５ｇ．ｇ－１、２９．３４μｍｏｌ·ｍｉｎ－１·ｇ－１、３８９．１７μｍｏｌ·ｍｉｎ－１·ｇ－１．也研究了各种物质对葡萄糖氧化酶及过氧化氢酶活力的影响，金属离子对葡萄糖氧化酶有抑制，阴离子对葡萄糖氧化酶和过氧化氢酶有抑制。
Biosynthesis of glucose oxidase and catalase by Aspergillus niger ZBY7 was studied. CaCO_3 was a particularly strong inducer of glucose oxidase and catalase. The models of their production were types of continuous synthesis. The maximum specific growth rate, growth yield coefficient, the glucose utilization coefficients (Y(GOD/S) and Y(CAT/S)) were respectively 0097 h-1,0075 g·g-1,2934 μmol·min-1·g-1,38917 μmol·min-1·g-1. Metal ion can inhibit glucose oxidase, anion can inhibit glucose oxidase and catalase,while reductive compounds can activate glucose oxidase.
