Enhancement of batch biohydrogen production from prehydrolysate of acid treated oil palm empty fruit bunch

► Study the feasibility of oil palm empty fruit bunch hydrolyzate as feedstock to produce biohydrogen. ► The acid concentration effects on the production of sugars and by-products. ► Evaluate the influence of pH parameter on biohydrogen production and metabolites formation. ► The simulation of biohydrogen performance using modified Gompertz equation.
