In this study, the biohydrogen production from POME was performed under mesophillic conditions by mixed culture in a 2 L bioreactor using the optimized conditions obtained previously. The effect of controlling pH initially or throughout the fermentation was also examined. The fermentation performance was monitored by comparing P, R<SUB>m</SUB>, &lambda;, and P<SUB>s</SUB> in both systems. In this present study, the reactor system showed higher hydrogen production potential values with the utilization of pH control. Hydrogen production potential was increased two folds when the reactor system was equipped with pH control rather than just fixed the initial pH at 5.8. The biohydrogen production under controlled pH occurred after 7 h fermentation resulting in maximum Ps and Rm of 1.32 L/L POME and 0.144 L/L.h, respectively.
