2-chloro-4-nitrophenyl-alpha-maltotrioside + H2O acid-stable amylase and common neutral amylase can degrade the substrate at pH 5.4 to release 2-chloro-4-nitrophenol. In presence of 500 mM KSCN the reaction rate of common neutral amylase increases markedly whereas the reaction rate of acid-stable amylase decreases Aspergillus niger 2-chloro-4-nitrophenol + alpha-maltotrioside
