酶促水解蔗糖生产果葡糖浆新工艺

A New Production Technique of Fructose and Glucose Syrup by Engymatic Hydrolysis of sucrose

以黑曲霉（Asp．niger－w1）为出发菌，经紫外诱变、亚硝基胍处理获得一蔗糖酶高产菌（Asp．niger－w3）。经固态发酵培养获高活力蔗糖酶。这酶在50～55℃有较高活力，在pH5．5～6．0范围内有较高稳定性。该菌种选育成功，可为果葡糖浆生产提出一种简易制备方法．

Sucrose producing strain W3 was obtained from strain W1 by means of UV and NTG mutageneses. The optimum for operation temperature or pH was 50~55℃ or 5. 5~6. 0 respectively. It provided a new approach to produce froctose corn syrup by biochemica1 technology.
