In this study, physical and chemical pretreatments were compared in terms of their enhancements in biomass enzymatic saccharification in reed. Steam explosion treatment results in 60.8% glucose conversion. In comparison, 1% H₂O₂ treatment along with steam explosion is a relatively low-cost biomass conversion method with glucose conversion at 80%. Sequential 1% H₂O₂ pretreatment with steam-exploded residues resulted in the highest ethanol yield at 16% with an almost complete sugar-ethanol conversion rate. Because of lower amount of non-cellulosic polymers (ligning, hemicelluloses) that increase the biomass surface, steam-exploded residues were specifically effective for 1% H₂O₂ either to block lignin absorption with cellulases or to disassociate hemicelluloses, leading to efficient enzymatic lignocellulose digestion. To our knowledge, this study provides three more applicable approaches for high ethanol production with relatively low cost, less contaminant release, and efficient biomass conversion rates in reed compared to previously reported pre-treatments in other C4-grasses (Miscanthus, corn, sweet sorghum, switchgrass).
