Abstract
Palm Oil Mill Effluent (POME) could become a very good carbon feedstock for hydrogen production in fermentation process if it is well prepared and being utilised based on its fermentable constituents composed in POME. In this research, the effectiveness of pre-treatment methods on POME was examined based on total carbohydrate (TC) and chemical oxygen demand (COD). Several pre-treatment methods such as heat, acid and alkaline were introduced to POME to increase the total carbohydrate content in POME medium. These mediums were further used in fermentation process to ensure the effect of pre-treatment method in term of hydrogen production. The highest hydrogen yield was 2.18 mol H2 / mol total carbohydrate given by POME using alkalineheat-supernatant pre-treatment in bioreactor 2L
