Abstract: Three glucoamylases, two debranching enzymes and two α-glucosidases were examined either singly or in combination with one another to breakdown isomaltose and panose which are produced during the hydrolysis of starch as byproducts, thereby leading to poor conversion efficiency. Such oligosaccharides rich fractions collected from starch industry or prepared from maltose by the transglucosylase action were used as substrates for enzyme action. Of these enzymes, the α-glucosidases, either singly or in combination with glucoamylase could breakdown panose and isomaltose completely at low substrate concentrations. The combination of glucoamylase and maltase (commercial product; α-glucosidase of Rhizopus origin) was found to be best in being able to hydrolyze these byproducts even at high glucose concentrations. The possibility of such an enzyme system being used in industry is discussed.
