The study of the effect of glucose addition to the kinetics of maltodextrin hydrolysis catalyzed with free and immobilized Aspergillus niger glucoamylase does not show any significant glucose inhibitory effect. This result is in contradiction with data previously reported in the literature. On the contrary, a slight glucose‐activating effect was observed. This effect was greater in the case of the immobilized enzyme. The glucose inhibitory effect may thus not be involved in the case of practical saccharification conditions catalyzed with glucoamylase when maltodextrins are used as substrate.
