WebNov 4, 2024 · Amylase derived from T. kodakarensis was having a molecular weight of 80 kDa. The enzyme showed optimum activity at 95–100 °C and pH 3.5. Even though it was more active at acidic pH, the enzyme retained most of its activity in alkaline pH also (Ahmad et al. 2014). The bacterial amylase enzyme with its characteristics is shown in Table 11.1. WebThis pH range is slightly basic and is similar to the pH of human saliva, which is why amylase is active in the mouth during the process of digestion. At pH values outside of this optimal range, the activity of alpha-amylase decreases significantly.
