Abstract
A fungal alpha-amylase is provided from(AfAmyl). AfAmyl has an optimal pH of 3.5 and is operable at 30-75 degrees C., allowing the enzyme to be used in combination with a glucoamylase and an isoamylase in a saccharification reaction. This obviates the necessity of running a saccharification reaction as a batch process, where the pH and temperature must be readjusted for optimal use of the alpha-amylase or glucoamylase. AfAmyl also catalyzes the saccharification of starch substrates to an oligosaccharide composition significantly enriched in DP2 and (DPI+DP2) compared to the products of saccharification catalyzed by an alpha-amylase from. This facilitates the utilization of the oligosaccharide composition by a fermenting organism in a simultaneous saccharification and fermentation process, for example.
