摘要：Biogas production from lignocellulose by anaerobic digestion has made significant progress lately. However, the bioconversion of lignocellulose is still hindered by its recalcitrant and heterogeneous structure. To overcome this challenge, a novel method of super diluted mixture alkali (SDMA) pretreatment was developed to enhance the biogas production from cornstalk in high -solid anaerobic digestion. The cornstalks treated with 2 g/L NH3 and 1 g/L NaOH achieved a cumulative methane yield of 241.50 mL/g VS, which was 184.65 % and 55.6 % higher than that of the untreated and 2 % NaOH treated cornstalks, respectively. The system stability was verified by a scaleup experiment in a 10 L bioreactor. Remarkably, the entire process does not generate any wastewater or chemical pollution. Moreover, the resultant biogas slurry could be directly applied as a concentrated bio-fertilizer. The findings are potentially beneficial for the development of the second -generation biogas industry from lignocellulosic biomass, which can provide both clean and economical bioenergy.
