Biosynthesis of oligodextrans with different Mw by synergistic catalysis of dextransucrase and dextranase

•Different adding times of dextranase on dextran sucrase system were investigated.•Oligodextrans composed of α-1,6-glycosidic linkages and low α-1,3-glycosidic branch.•P. aculeatum dextranase preferentially degraded dextran with higher molecular weights.•COSY and HSQC spectra clearly showed the inte...
