Comparison of HPAEC-PAD profiles of the product mixtures of different GTFB preparations. 50 mM maltose (a) and maltotriose (b) were seperately incubated with GTFB preparations with equal hydrolysis activity (25.0 μg/ml soluble GTFB, 38.7 μg/ml refolded GTFB and 249.4 μg/ml 25 °C ncIB GTFB) after 72 h at 37 °C and pH 4.7. The oligosaccharide structures produced were identified (c) according to Dobruchowska et al. [2]. G1 to G7 represent glucose, maltose, maltotriose, maltotetriose, maltopentaose, maltohexaose and maltoheptaose, respectively
