PROBLEM TO BE SOLVED: To form ethanol by simultaneously carrying out saccharification and fermentation of scrap onions in a single tank. SOLUTION: The ethanol is formed by preparing immobilized yeast, by including an yeast by calcium alginate, mixing the pulverized onion with the immobilized yeast in the same tank, and simultaneously carrying out the saccharification of the onion, and the fermentation of the formed sugar. The calcium alginate prevents a fermentation-inhibiting material contained in the onion from penetrating into the immobilized yeast and from contacting with the yeast, and allows the sugar to permeate the calcium alginate and to contact with the yeast so as to carry out alcohol fermentation.
