主 题:Cellulosic biomass dilute acid pretreatment and enzymatic hydrolysis sugarcane shoots and leaves ethanol production.
摘 要:Sugarcane shoots and leaves consist of 38% cellulose, 30.6% hemicellulose and 12.8% lignin on dry solid (DS) basis and have the potential to serve as low cost feedstocks for ethanol production. The pretreatment and enzymatic hydrolysis conditions include particle size, alkali (NaOH)/dilute acid (H2SO4) pretreatment, chemical and substrate concentrations, temperature, autoclaving time for pretreatment, enzyme concentration, pH and temperature for hydrolysis varied were evaluated for conversion of sugarcane shoots and leaves cellulose and hemicellulose to reducing sugar. The optimum conditions were accomplished by using 14% w/v DS of 0-10 mm sugarcane shoots and leaves in particle size, pretreated with 1.5% w/v of dilute sulfuric acid at 121℃, 15 lbs/in2 for 15 min and enzymatic saccharification using 40 FPU/g DS cellulose at 50℃ and pH 5, After incubating at 160 rpm for 12 hrs, 59 g/L or 386,38 mg/g DS of reducing sugar and 50.69% saccharification were obtained.
