The efficient enzymatic conversion of cellulosic biomass depends heavily on the effectiveness of the pretreatment step. During pretreatment, the impeding layers (usually lignin and hemicellulose) in the biomass are removed or disrupted, and the cellulose becomes easily accessible to enzymes. A variety of pretreatment methods have been developed, differing significantly from one another in terms of reaction conditions, process efficiency and complexity, and impact on subsequent enzyme and microbial processes. This review presents the pretreatment techniques to enhance the anaerobic digestion of organic solid waste, including mechanical, thermal, chemical and biological methods. The effects of various pretreatment methods are discussed independently and results of some pretreatment are discuss from research work.
