The CMCase assay will be modified from the method of activity Sengupta et al (2000). Enzyme solution of 0.5 mL will be added in 0.5 mL of 1% (w/v) CMC solution in 0.05M CP buffer incubated at 45 ℃, for 30 minutes. Stopped the enzymatic reaction will be added of 1.0 mL of dinitrosalicylic acid (DNS) and and then boiled for 10 minutes and then soaked in cold water will be followed by adding the deionized water of 5.0 mL into the mixture, then measured spectrophotometric at 540 nm. The sample will be compared to standard glucose and calculation of enzyme activity. One unit (U) of CMCase activity was defined as the amount of enzyme that hydrolyzed CMC to yield 1 µmol of reducing sugar per minute under the experimental condition.
