Co-fermentation of palm oil mill effluent (POME) for hydrogen production by Thermoanaerobacterium thermosaccharolyticum PSU-2 under thermophilic condition was investigated. Hydrogen production from co-fermentation POME with 5 g/L decanter cake and without was 2.6 and 1.7 L-H<SUB>2</SUB>/L-POME. Co-fermentation of POME with decanter cake enhanced hydrogen production. Tbm. thermosaccharolyticum PSU-2 augmentation at 20% v/v was found to be an efficient start-up strategy in continuous hydrogen production from co-fermentation of POME with decanter cake. Tbm. thermosaccharolyticum PSU-2 augmentation could suppress normal flora bacteria in POME and decanter cake. Hydrogen production of 7.2 L-H<SUB>2</SUB>/L-POME and hydrogen production rate of 18.1 mmol-H<SUB>2</SUB>/L/h was achieved from continuous hydrogen in long term operation. The soluble metabolites were dominated by acetic acid and butyric acid. Tbm. thermosaccharolyticum PSU-2 augmentation could use for control undesired bacteria in the hydrogen production system with flavored Thermoanaerobacterium sp. as dominant species.
