Cover Story: Recalcitrant nature of the lignocellulosic biomass due to its heterogeneous structure is one of the major limitations for its use as a feedstock in anaerobic digestion process. Feedstocks with lower lignocellulosic content can be fed directly to anaerobic biodigesters, whereas pretreatment is necessary when lignocellulose content is higher. However, intermediaries formed during pretreatment process are known to show an adverse effect on methanogenesis. This review highlights the efficiency and limitations of the different pretreatment methods from engineering, chemical, and biochemical point of views to increase the carbon recovery as methane from lignocellulosic biomass.
