Abstract
The effect of ultrasound on hydrolysis
of amylopectin by isoamylase were
investigated. Ultrasound without agitation
can enhance reaction with the similar rate to
that in the shaker. Thus, it implied that
ultrasound may enhance mass transfer.
Besides, reaction rate is linearly related to the
ultrasound intensity when intensity higher
than 0.005W/ml. According to kinetic
investigation in the cleaning bath system,
Vmax increases to 1.9 times and Km to
increases 4.1 (power=7) and 4.5 (power=9)
times respectively. For probe system, reaction
rate enhancement may actually result from amylopectin degradation under ultrasound,
therefore it is hard to discuss its kinetic
property.
