Leban.—This sour aromatic drink is very closely similar to mazun and is made from boiled buffalo's, cow's and goat's milk. It is of Egyptian origin. It is said to contain less alcohol than does kephir. Leban fermentation is due to a streptobacillus which coagulates milk and forms lactic acid. A diplococcus is also present which ferments glucose, saccharose and maltose. A strep-. Fig. 82.—Sarcina ventriculi.—(McFarland, after Migula.) tococcus hydrolyzes lactose and another organism is capable of fermenting glucose and maltose but not lactose. 12. Ginger Beer.—This is a fermented sugar solution to which ginger has been added. The essential fermenting organisms are a saccharomyces (S. pyriformis) and Bacillus vermiforme. My co- derma aceti is also present. The two essential organisms are evidently in close mutualistic relationship. The drink produced is acid and effervescing. The so-called ginger beer plant is simply a mass or matrix of the active organisms and is used for the purpose.
