Abstract
Continuous fermentation with yeast to produce alcohol is carried out by continuously passing a carbohydrate-containing substrate liquid through a vessel packed with a thin film means having yeast immobilized therein. Surfaces of the thin film means extend in the direction of flow within the vessel to provide elongated parallel passages. The thin film means occupies from 10 to 65% of the volume of the vessel and preferably has a thickness of 0.1 to 3 mm. Preferably, the thin film means is formed by mixing an aqueous yeast suspension with a photo-crosslinkable resin and subjecting the mixture to radiation to photo-crosslink the resin.
