Abstract

In this study, the biohydrogen production by microflora of palm oil mill effluent (POME) from glucose and xylose fermentation were investigated. Synthetic medium was prepared based on sugar composition present in POME at 7 g/L of glucose and 3 g/L of xylose was used as substrate carbon source. Prior to optimization, 10% of microflora POME was acclimatized in the synthetic medium with the help of granular activated carbon as their support media until consistent hydrogen percentage at 44 ± 1.7% was obtained. Optimization that was conducted using response surface methodology (RSM) by quadratic model of central composite design was found to give optimum parameters of thermophilic microbial growth at pH 6, temperature 60 °C and 10% (v/v) of sludge percentage. Results obtained for hydrogen productivity (1.32 ± 0.01 mmol H2/L.h, 32.36 ± 0.75 ml H2/L.h) and hydrogen yield (1.22 ± 0.10 mol H2/mol sugar consumed) from an average of experimental data reached small error of different (0.8%, 1.0% and 8.3%) to predicted RSM data at optimum condition respectively. The model provided a useful approach for biohydrogen production by POME microflora sludge by using granular activated carbon as their support media.
