Effect of carbohydrate source on alpha-amylase and glucoamylase formation byClostridium acetobutylicum SA-1

Abstract

An examination into the effect of different carbohydrate sources indicated that the production of extracellular alpha-amylase and glucoamylase was under similar biosynthetic control in Clostridium acetobutylicum SA-1. Cell-associated starch-hydrolytic enzymes may be more important than extracellular enzymes in the processing of the starch molecule.
