Fig. 8From: Elucidating the degradation pattern of a new cold-tolerant pectate lyase used for efficient preparation of pectin oligosaccharidesESI-MS analysis of the degradation products of ErPelPL1 towards polygalacturonic sodium. The mass-to-charge ratios (m/z) of oligosaccharide products were detected by using ESI-MS. ΔDPn (n = 1–6) represents unsaturated oligosaccharides with DP of 1–6Back to article page
