WebIn addition, cPMO2 owned a broad substrate specificity, which could act on PASC and xylan at the C1 site based on the MALDI-TOF-MS analysis results. Simultaneously, cPMO2 could also act on Avicel directly resulting the decrease of crystallinity by 4% and further to synergistic degradation of corncob and rice straw with glycoside hydrolases. WebBecause the pure xylan was degraded much more rapidly (k = 0.52 h −1) by the same inocula, it appears that the rate of xylan degradation in the composite was due to its limited accessibility when surrounded by cellulose. Despite this, both components were ultimately degraded completely, in the absence of lignin.
