title: [Industrial scale-up of continuous ethanol fermentation using yeast flocs].
abstract: Inducing yeast cells to self-flocculate as a cell immobilization method, an industrial scale-up plant composed of 4 air-lift suspended-bed bioreactors in parallel and with a total volume of 400 m3 was established and operated. During a more than 6 months continuous operation, the effluent contained ethanol of 70-80 g/L and residual sugar less than 5 g/L and the ethanol productivity of 7-8 g/L.h-1 was achieved.
