Abstract

Abstract:

The effects of N,N-dialkylimidazolium-based ionic liquids on the catalytic reaction of amylase were studied in this paper via the spectroscopy method. The results indicate that the ionic liquids show inhibitory activities on the catalytic reaction of amylase. 1-Butyl-3-methylimidazolium chloride([HMIM]Cl) showed the highest inhibitory activity among all investigated ionic liquids in this study. Furthermore, the inhibition effect of ionic liquids having the same anion increases with the alkyl group length of the imidazolium ring.

Key words: ionic liquid, amylase catalyzing, spectrophotometry, inhibition
