METHOD OF USING ALPHA-AMYLASE FROM ASPERGILLUS CLAVATUS AND ISOAMYLASE FOR SACCHARIFICATION. |
摘要 |
A fungal alpha-amylase is provided from Aspergillus clavatus (AcAmy1). AcAmy1 has an optimal pH of 4.5 and is operable at 30 - 75°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. AcAmy1 also catalyzes the saccharification of starch substrates to an oligosaccharide composition significantly enriched in DP2 and (DP1 + DP2) compared to the products of saccharification catalyzed by an alpha-amylase from Aspergillus kawachii. This facilitates the utilization of the oligosaccharide composition by a fermenting organism in a simultaneous saccharification and fermentation process, for example. |
