Abstract

The recalcitrance of lignocellulosic poses a challenge for conversion to biogas and therefore, pretreatment is an essential step in addressing this. Combining fungal pretreatment with a biomimetic system, a mild Fenton reaction, was studied to improve the methane production from straw. The pretreatment conditions studied were able to reduce lignin content and cause an increase in the relative polysaccharides content. Interestingly, variations among the strains of the same species were observed in their ability to improve the biomethane yield. The order of pretreatment combination also played an important role as it affects the mechanism of action of subsequent pretreatment on the biomass, which indirectly affects the biogas yield.
