Abstract

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.

Résumé

La production de gluco-amylase est induite chezAspergillus terreus, en ordre décroissant, par le glucose, le celloboise, le sorbitol, le sucrose, l'α-methylmannoside et l'α-methylglucoside. L'induction est optimum à 38°C, pH 4.0 et en présence de 8 mg de glucose parml. La cycloheximide à 10 μg par ml inhibe complètement l'induction, ce qui implique use synthèse de protéinede novo dans l'induction de la gluco-amylase.
