Optimal temperature for alpha amylase
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%. 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 ...
