Dilute Acid Hydrolysis Of Oil Palm Empty Fruit Bunches, Rice Husks, Rice Straws And Oil Palm Trunks To Produce Glucose And Xylose

Lignocellulose biomass are potential renewable sources to produce biofuels that may replace the non-renewable fossil fuels. Oil palm empty fruit bunches (EFB), oil palm trunks (OPT), rice husks and rice straws were used to produce fermentable sugars via acid hydrolysis. Glucose enzymatic assay wa...
