Abstract/OtherAbstract:
Combination of liquid hot water pretreatment (LHWP) and wet disk milling (WDM) was investigated in this study to enhance the sugar recovery yield both in prehydrolyzate and enzymatic hydrolyzate. The results show that WDM with LHWP at 180°C for 20min produced maximum xylose and glucose yields of 91.62% and 88.12%, respectively, which are higher than that of dilute acid pretreatment or individual LHWP. Corresponding concentration of fermentation inhibitors such as acetic acid, HMF, and furfural in the prehydrolyzate are about 0.98, 0.07 and 0.78g/L, respectively, which indicated that the detoxification may be not required in the next fermentation step. The acid-insoluble lignin recovery in the insoluble solid resulting from enzymatic hydrolysis, was 25.67/100g raw material, representing 90.7% of acid-insoluble lignin in the eucalyptus biomass. It can be concluded that liquid hot water pretreatment combined with wet disk milling can be successfully applied to eucalyptus.
