Xylanase properties.

Note: Topt: optimal reaction temperature for activity, t1/2: thermal in-activation half-life, after incubation at 50°C for different intervals, residual activity was determined and expressed as a ratio to the un-incubated enzyme, and data were fitted with Arrhenius function. The t1/2 was calculated according to the decay function to indicate enzyme thermostability. Using the Student’s t-Test (popt and Topt conditions, and the data were fitted with Hill function to calculate Vmax and Km.
