Efficient ethanol production from paper mulberry pretreated at high solid loading in Fed-nonisothermal-simultaneous saccharification and fermentation

摘要: Abstract Paper mulberry, a fast-growing and vigorous plant, is potential substrate for producing lignocellulosic bioethanol an important renewable alternative to fossil fuels. In order improve the economic feasibility of ethanol production from paper H3PO4/H2O2 pretreatment was selected as most suitable method that could produce highest glucose concentration (131 g/L) compared with other pretreatments (73.2–89.3 g/L) at high solid loading. Whereafter, final loading significantly increased 40% (w/v) without any decrease in concentration. Finally, novel Fed-nonisothermal-simultaneous saccharification fermentation constructed using pretreated which bypassed inhibition caused by mulberry temperature on traditional simultaneous fermentation, improving (63.9 g/L), productivity (1.33 g/L/h) yield (0.160 g/g-biomass) 30.4%, 30.4% 30.1%, respectively, those obtained SSF (simultaneous fermentation) process. Thus, we have opened up way or biofuels outstanding substrate.
