PURPOSE:To improve the yield of an alcohol from a raw material saccharide, by arranging two fermenting devices of the fluidized bed type in series, by cultivating a bacterium capable of fermenting an alcohol attached to a carrier by the former fermenting device and a flocculating yeast by the latter. CONSTITUTION:For example, a solution of waste molasses diluted by five times is fed through the pump 3 to the fermenting device 1 of the fluidized bed type, it is circulated through the pump 4, the solution of waste molasses overflown from the top of the device 1 is fed through the pump 5 to the fermenting device 2 of the fluidized bed type, and circulated through the pump 6. A bacterium capable of fermenting an alcohol, attached to a carrier, is cultivated in the fermenting device 1, and a flocculating yeast in the fermenting device 2. The solution of waste molasses is subjected to alcohol fermentation by the two, to improve the yield of an alcohol. The fermented solution having finished fermentation is continuously taken out from the top of the fermenting device 2. |
