Figure 5: (A) Effect of pH on amylase activity (B) Effect of pH on amylase stability. (Solid diamond) denotes activity at 0 min; (Solid square) denotes activity after 30 min incubation; (Solid triangle) denotes activity after 60 min incubation. (C) Effect of temperature on amylase activity (D) Thermostability of amylase after preincubating for 30 min.
