摘要：
The present invention relates to a novel pullulanase, a method of producing it and a method of saccharifying starch using it. The pullulanase of the invention can work over pH range as wide as pH4-9, is heat stable and has an optimum temperature of about 60°C. The pullulanase of the invention can be used along with an amylase, which is enzymatically active at pH4-9, to increase the yield of saccharides from starch.
摘要（中）：
本发明涉及一种新型支链淀粉酶，其制备方法以及使用该淀粉糖化淀粉的方法。 本发明的支链淀粉酶可以在pH4-9的pH范围内工作，具有热稳定性并且具有约60℃的最适温度。本发明的支链淀粉酶可以与pH4的酶活性淀粉酶一起使用 -9，以增加淀粉中糖类的产量。
