Cell immobilization techniques were adopted to bio-hydrogen production using immobilized anaerobic sludge as the seed culture. Palm oil mill effluent (POME) was used as the substrate carbon source. It was found that with a POME concentration of 20g COD/l in the feed, the suspended-cell containing reactor was able to produce hydrogen at an optimal rate of 0.348l H<SUB>2</SUB>/(l POME h) at HRT 6h. However, the immobilized-cell containing reactor exhibited a better hydrogen production rate of 0.589l H<SUB>2</SUB>/(l POME h), which occurred at HRT 2h. When the immobilized-cell containing reactor was scaled up to 5l, the hydrogen production rate was 0.500-0.588l H<SUB>2</SUB>/(l POME h) for HRT 2-10h, but after a thermal treatment (60<SUP>o</SUP>C, 1h) the rate increase to 0.632l H<SUB>2</SUB>/(l POME h) at HRT 2h. The main soluble metabolites were butyric acid and acetic acid, followed by propionic acid and ethanol.
