. Bacteria, yeasts and molds in the home. Bacteriology; Yeast fungi; Molds (Fungi). go BACTERIA, YEASTS, AND MOLDS elderberries, blackberries, currants, raspberries, etc. Cider also is an apple wine.

It must be remembered that in the United States their sale or transportation is distinctly illegal. Whatever be the source of the yeast, the process of wine making is simply an ordinary fermenting of the sugar. The carbon dioxide that is produced is allowed to pass off into the air undis- turbed during the fermenta- tion, and the liquid gradually becomes filled with alcohol. The final result is the wine, which always contains alcohol in small percentage. After the yeasts stop grow- ing, bacteria may develop in the product and cause fur- ther changes, so as to injure its taste, or even totally change its nature, as in the forma- tion of vinegar. (See Chapter XI.). Fig. 37. Organisms found upon the skin of a grape and concerned in the fermentation of wine. The Use of Yeasts as a Source of Carbon Dioxide The chief use of yeasts in the household is not to pro- duce fermented drinks but to raise bread. The raising of bread by means of yeast has been brought to a state of great perfection, so that the method of producing a desir- able fermentation in bread dough by means of this product.
