Effect of carboxymethyl groups on degradation of modified pullulan by pullulanase from Klebsiella pneumoniae

► Pullulanase type I degrades pullulan to give maltotriose. ► Pullulan grafting by carboxymethyl groups is resistant to this enzymatic treatment. ► The resistant is favored by high substitution of pullulan. Pullulanase is an enzyme that hydrolyses the α-1,6 linkages of pullulan (Pull) to produce mal...
