A continuous alcohol manufacturing process using yeast comprising a zone where a conventional yeast (Yeast B) which has an alcohol producing activity is mainly present (zone of Yeast B); a zone disposed in the fore part of said zone of Yeast B where a yeast (Yeast A) which has an alcohol producing activity and is superior in sugar resistance as compared with Yeast B is mainly present (zone of Yeast A); and a zone disposed in the rear part of said zone of Yeast B where a yeast (Yeast C) which has an alcohol has an alcohol producing activity and is superior in alcohol resistance as compared with Yeast B is mainly present (zone of Yeast C), wherein a substrate solution is supplied to said zone of Yeast A thereby to effect alcohol fermentation; the resulting fermentation liquid is introduced in said zone of Yeast B thereby to effect alcohol fermentation; the resulting fermentation liquid is further introduced in said zone of Yeast C thereby to effect alcohol fermentation; and then a product alcohol broth is obtained from said zone of Yeast C.

Continuous alcohol manufacturing process using yeast

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.
