AB  - Getting over recalcitrance of lignocellulose is effective way to fuel production 
      from lignocellulosic biomass. In current work, different pretreatments were 
      applied to enhance the digestibility of corn stover (CS). Results showed that 
      steam explosion (SE)-treated CS produced maximal methane yield (223.2 mL/gvs) at 
      1.2 MPa for 10 min, which was 55.2% more than untreated (143.8 mL/gvs). Whereas 
      1.5% KOH-treated CS produced maximum methane yield of 208.6 mL/gvs, and 
      significantly (alpha<0.05) improved 45.1% with respect to untreated. Sequent 
      pretreatment of potassium hydroxide and steam explosion (SPPE) (1.5% KOH-1.2 MPa, 
      10 min) achieved a very significant (alpha<0.01) improvement (80.0%) of methane yield 
      (258.8 mL/gvs) compared with untreated CS. Methane production could be well 
      explained by the first-order and modified Gompertz models. Besides, SEM, FTIR, 
      and XRD analyses validated structural changes of CS after SPPE. SPPE might be a 
      promising method to pretreat CS in the future AD industry.
