温度和pH对鹅肠道细菌纤维素酶活力的影响

Effect of Temperature and pH on Activity of Bacterial Cellulase from Geese Intestinal Tract

试验设计不同温度和pH，测定鹅肠道细菌纤维素酶活力。来源于回肠的菌株H14在60℃、pH值6．0时，酶活力最大为41．4U；来源于盲肠的菌株M3在60℃、pH为4．0时，酶活力最大为51．4u。

Different temperature and pH was adopted to determine activity of bacterial cellulose in geese intestinal tract. The results showed that the strain H1 in ileum reaches best enzyme activity 51.4 U at 60℃, pH 6.0; The strain M3 in caecum reaches 41.4U at 60℃, pH4.0.
