hydrolysis of polysaccharides by alpha-amylase yielded as reaction products maltose , maltotriose , maltopentaose and maltohexaose , but no free glucose . beta-amylase produced as main degradation product of glucopolysaccharides maltose and to a minor extend maltotriose , but no glucose . alpha- and beta-amylase were able to hydrolyze 4-nitrophenyl-alpha-d-glucooligosaccharides ( gn-pnp ) containing more than two glucose units per molecule .
