Benefits of Bacillus megaterium Amylase in Dextrose Production

Abstract

A Bacillus meguterium amylase (BMA) has the ability to convert branched saccharides to a form that is easily hydrolyzed by glucoamylase. Concequently, dextrose production can be improved by using a combination of BMA and glucoamylase in saccharification. Benefits provided by BMA are similar to those achieved with a debranching enzyme. For instance, BMA is effective in increasing dextrose yield, while at the same time, nearly eliminating tetra‐ and higher saccharides. BMA can also be used to increase saccharification rate, reduce glucoamylase dosage, or maintain normal dextrose level at higher solids. Benefits of BMA have been quantified by evaluating the enzyme in combination with glucoamylase using typical industrial saccharification conditions.
