<P>α-Amylase activities of Aspergillus oryzae grown on dextrin or indigestible dextrin were 78 and 277?U?ml(-1), respectively. Glucoamylase activities of the cultures grown on dextrin or indigestible dextrin were 54 and 301?mU?ml(-1), respectively. The specific glucoamylase production rate in indigestible dextrin batch culture reached 135?U?g?DW(-1)?h(-1). In contrast, biomass concentration of A. oryzae in indigestible dextrin culture was 35% of that in dextrin culture. Thus, the culture method using indigestible dextrin has the potential to improve amylolytic enzyme production and fungal fermentation broth rheology.</P>
