Intensification of biobutanol production in batch oscillatory baffled bioreactor

A novel intensified bioreactor called the oscillatory baffled bioreactor (OBB) was evaluated for biobutanol production. Batch acetone-butanol-ethanol (ABE) fermentations were conducted in OBB at various oscillatory Reynolds numbers (0-1870) and in stirred tank reactors (STR) at various stirrer speed...
