Bio-hydrogen is a promising sustainable energy to replace fossil fuels. This study investigated bio-H<SUB>2</SUB> production from the inoculum of heat-pretreated landfill leachate sludge using glucose as model substrate. The seed sludge pretreated at 65 <SUP>o</SUP>C showed the highest amount of H<SUB>2</SUB> at the optimum condition of pH 6 and 37 <SUP>o</SUP>C. The maximum H<SUB>2</SUB> yield estimated by the modified Gompertz model was 6.43 mol H<SUB>2</SUB>/mol glucose. The high efficient of H<SUB>2</SUB> production is thermodynamically feasible with the Gibbs free energy of -34 kJ/mol. This study reveals that pretreated landfill leachate sludge has considerable potential for H<SUB>2</SUB> production.
