Cellulase is one of the industrial production and agricultural production indispensable enzymes, cellulase enzymes are not single, but by endoglucanases, exoglucanases and β-glucosidase enzyme composition and generally cellulases also contain high levels of xylanase activity, the synergistic effect of these enzymes can be successfully decomposed crystalline cellulose. But to cellulase can play a better role, the role of the condition that there are strict requirements, optimum conditions are different cellulases are different, too acid, too alkaline and heat will cause the cellulase enzyme inactivation. So what the optimum conditions are generally cellulase is it?

1, acid cellulase optimum conditions: optimum pH: 3.5-4 optimal temperature: 45-55 ℃

2, neutral cellulase optimum conditions: Optimum pH: 4.5-6 optimal temperature: 45-55 ℃

3, alkaline cellulase optimum conditions: optimum pH: 10-11 The optimal temperature: 45-55 ℃

Of course not rule out some special bacteria fermentation of cellulase have exceptions optimum conditions, the optimum conditions for cellulase species will depend on their structure and their living environment.
