Hydrogen is an excellent energy option; a clean energy alternative with no emission of greenhouse gases; which helps in addressing the challenge of global climate change. Acidogenic bacteria decompose organic substances to hydrogen and carbon dioxide, making it a merit for treating most organic wastes from industry. In Malaysia, palm oil industry generates 50 million tonnes of wastewater or POME annually. This could be a source for hydrogen gas production. The objectives of this research are to optimize the production operation and genetically manipulate the hydrogen-producing bacterial strains to get higher yield. Currently, we managed to optimize the culture conditions based on statistical experiment design, where we found that the optimum pH for cultivation of lostridium butyricum was at pH 6.0 with the POME at 90 gCOD/L. Concurrently, we developed reactor system for hydrogen gas production from POME using natural microflora at mesophilic and thermophilic conditions. We are focusing now on shortening the hydraulic retention time in the continuous treatment of POME for biohydrogen production. Both systems are stable and the results were comparable with the current systems carried out by the different research sub-groups in collaborating institutions, i.e. University Malaya, University Kebangsaan Malaysia and the Standards and Industrial Research Institute of Malaysia (SIRIM).
