Microcalorimetric Study on Enzyme Catalyzed Hydrolysis Reaction of Starch
Abstract:
The thermal power-time relation of starch hydrolysis reaction catalyzed by hydrolytic enzyme has been evaluated using a microcalorimeter. The maximum velocity(Vmax) was calculated according to the equation Vmax=[-2.975 79×10-4+2.401 91×10-4 pH-6.940 00×10-5 pH2+ 9 040 00×10-6 pH3-4 450 00×10-7pH4] g/(dm3·s).The optimum acidity was found to be pH=5.78.
