HPAEC-PAD profile of the oligosaccharide mixture formed upon the incubation of L. reuteri NCC 2613 GtfB-ΔN (20 μg ml−1) with maltoheptaose for t = 1 h, 3 h and 24 h (pH 5.5, 37 °C). The identity of peaks was assigned using commercial oligosaccharide standards. G1, glucose; G2–G7, maltose to maltoheptaose; iso-G2, isomaltose; and iso-G3, isomaltotriose.
