Abstract
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.
