Production and Biochemical Characterization of a High Maltotetraose (G4) Producing Amylase from Pseudomonas stutzeri AS22
Figure 4
Temperature profile (a) and thermal stability (b) of P. stutzeri crude enzyme. Amylolytic activity was assayed at different temperatures ranging from 20 to 90°C at pH 8.0. The activity of the enzyme at 60°C was taken as 100%. To assess the thermostability, the P. stutzeri crude enzyme was heated at the indicated temperatures. The residual activity was assayed at pH 8.0 and 60°C. The nonheated crude enzyme was considered as the control (100%).
