Xylo-oligosaccharide oriented biorefining of corncob through citric acid/sodium citrate buffer hydrolysis and enzymatic upgrading
Selective production of xylo-oligosaccharides (XOS) from corncob is hindered by secondary degradation during acid hydrolysis. Here, a citric acid/sodium citrate (CA/SC) conjugate acid-base system was developed for XOS-oriented fractionation of corncob. Compared with the citric acid hydrolysis, the optimal CA/SC hydroly...
