PURPOSE:To improve the yield of alcohol from the sugar used as a raw material, by culturing bacteria having alcoholic fermentation capability and attached to a carrier together with immobilized yeasts in one fluidized layer fermentor. CONSTITUTION:For example, blackstrap molasses diluted to 5 times volume is supplied to a fluidized layer fermentor 1 with the pump 2, and at the same time, the blackstrap molasses is circulated with the pump 3. Bacteria having alcoholic fermentation capability and attached to a carrier such as pulverized vermiculite, activated charcoal, zeolite, etc. are cultured together with alcoholic fermentation yeasts included in and immobilized with polyacrylamide, sodium alginate, etc. in the fermentor 1 under fludizing conditions. The yield of alcohol can be improved by the combined action of the bacteria and the yeasts. After the fermentation, the fermented liquid is discharged continuously from the top of the fermentor 1. |
