Optimal temperature for alpha amylase
WebThe optimal temperature for amylase production and growth of the B. licheniformis were found to be different. The maximum amylase production was observed after 18-24 h and 36-48 h, when grown at ... WebMicrobial thermostable α-amylases have the optimum temperature and pH ranging from 50 °C to 100 °C and 5.0 to 10.5, respectively. These enzymes have high specificity towards potato starch, wheat starch, amylose, and amylopectin. EDTA (1 mM) gave the highest inhibitory effect (79%), but Ca2+ (5 mM) was the most effective co-factor with 155%.
