Pseudo-lignin and pretreatment chemistry
Web酶预处理过程中加入乙醇提高了酶解效率，有效提高了预处理木质素的溶解度和木质素的解聚度（DD）。. 酶解预处理增加了丁香基（S）型芳香族单体的含量，这阻碍了聚合产物之间的再缩合。. 由于木质素在酸性水溶液中的溶解度低，因此将乙醇加入酶解体系中 ... WebJan 16, 2024 · Schmatz et al. conducted a detail study on the formation of pseudo-lignin using different structural parts of sugarcane bagasse under several process conditions, and it was observed that the extractive-free biomass leads to produce less amount of pseudo-lignin prior to the acid pretreatment compared to that of the raw biomass. In addition, co ...
