Induction of glucoamylase production by non-starchy carbohydrates inAspergillus terreus.

Glucoamylase production inAspergillus terreus was induced, in order, by glucose, cellobiose, sorbitol, sucrose, α-methyl mannoside and α-methyl glucoside. Optimal induction was at 38°C, pH 4.0 and with 8 mg glucose/ml. Cycloheximide at 10 μg/ml completely inhibited induction indicatingde novo protein synthesis was involved in induction of glucoamylase.
