Optimal temperature for alpha amylase
WebOptimum temperature and pH were shown determined by noting where absorbency was the lowest because this is where the enzyme catalyzed the most amount of starch. The results showed that alpha amylase most efficiently converts starch into glucose at a temperature of 65 C and pH of 5. Therefore, alpha amylase works best in mildly acidic conditions ... 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 ...
