Solvent Fermentation from Palm Oil Mill Effluent using Clostridium acetobutylicum in Oscillatory Flow Bioreactor (Penghasilan Pelarut dari Fermentasi Efluen Loji Minyak Sawit oleh Klostridium Asetobutilikum di dalam Bioreaktor Aliran Berayun)

Acetone-butanol-ethanol (ABE) fermentation from Palm Oil Mill Effluent (POME) by C. acetobutylicum NCIMB 13357 in an oscillatory flow bioreactor was investigated. Experimental works were conducted in a U-shaped stainless steel oscillatory flow bioreactor at oscillation frequency between 0.45-0.78 Hz and a constant amplitude of 12.5 mm. Fermentations were carried out for 72 hr at 35oC using palm oil mill effluent and reinforced clostridia medium as a growth medium in batch culture. Result of this investigation showed that POME is a viable media for ABE fermentation and oscillatory flow bioreactor has an excellent potential as an alternative fermentation device.
