Biodegradation kinetics during the anaerobic digestion of untreated and corn stover, pretreated at two different intensities, 140°C for 5min and 180°C for 5min, were studied in tandem. Results showed that pretreatment at 160°C for 2min improved the methane yield by 22%. Harsher pretreatment conditions led to lower hemicellulose contents and methane yields, as well as higher lignin contents, which may be due to the formation of pseudo-lignin. The biodegradation kinetics trial demonstrated that steam explosion enhances the degradation of structural carbohydrates and acid insoluble lignin.eninfo:eu-repo/semantics/closedAccessAgricultural residuesAnaerobic digestionBiofuelBiomassMaize strawCorn stover for biogas production: Effect of steam explosion pretreatment on the gas yields and on the biodegradation kinetics of the primary structural compoundsWissenschaftlicher Artikel2884708510.1016/j.biortech.2017.08.0422-s2.0-85027859957http://www.scopus.com/inward/record.url?eid=2-s2.0-85027859957&partnerID=MN8TOARS
