Abstract

As found during continuous cultivation of Bacillus licheniformis on a semisynthetic medium (glucose or maltose as C source), the specific rate of alpha-amylase production is proportional to growth rate but is repressed by higher substrate concentrations. Besides glucose or maltose, peptone was also used as an alternative carbon source during cultivation. The specific rate of production of the enzyme on maltose is half that found with glucose.

摘要

在以半合成培养基（葡萄糖或麦芽糖作为碳源）连续培养地衣芽孢杆菌的过程中发现，α-淀粉酶的比生产速率与生长速率成正比，但会受到较高底物浓度的抑制。除了葡萄糖或麦芽糖外，蛋白胨在培养过程中也被用作替代碳源。该酶在麦芽糖上的比生产速率是在葡萄糖上的一半。
