摘要
用DNS为显色剂,以滤纸和CMC为底物,测定纤维素酶A的滤纸酶活和CMC酶活(PA和CMCA),探讨纤维素酶A的主要酶学性质。结果表明:FPA和CMCA的最适温度范围为50℃～60℃和50℃～70℃;最适pH为5.0和4.6～5.0。
The characteristics of cellulase a were investigated such as temperature dependence pH range, thermo - stability and pH - stability. The experiment results showed that the optional temperature and pH range are 50 - 551 and 5.0 respectively when filter - paper is used. It was found that cellulase a car maintain good stability in acid condition.
