英文摘要

a woody (eucalyptus (eu)) and two herbaceous materials (sweet sorghum bagasse (ssb) and sugarcane bagasse (scb)) were used to evaluate the effect of liquid hot water (lhw) pretreatment on enzymatic hydrolysis of various lignocelluloses. the results showed that enzymatic hydrolysis efficiency of pretreated materials was scb>ssb>eu at 5% solids loading, while ssb>scb>eu was at 10% and 20% solids loadings. this indicated the enzymatic hydrolysis efficiency of scb could be influenced by solids concentration. the differences in surface morphology, crystalline structure, and functional groups of pretreated samples were also examined by scanning electron microscopy (sem), xray diffraction (xrd), and fourier transform infrared (ftir) spectroscopy. sem photographs and crystallinity indexes (cri) showed that the structural compactness was eu>ssb>scb for both of untreated and treated materials. ftir spectra showed that the conspicuousness of physicochemical changes was scb>ssb>eu. the differences in enzymatic hydrolysis efficiency of pretreated materials can be ascribed mainly to the structural differences.
