Optimum temperature of invertase
WebIn contrary to most other enzymes, invertase exhibits relatively high activity over a broad range of pH (3.5--5.5), with the optimum near pH=4.5. The enzyme activity reaches a … Webtemperature of 37ºC for 30 minutes. After the 30 minutes, invertase activity was determined by reducing sugar dosage (MILLER, 1959). Invertase activity was evaluated through the parameters pH (3.5 to 9, with 0.5 unit intervals), temperature (17 to 57, with 10ºC intervals) and sucrose concentration (0, 10, 20, 50, 100 and 200
