a soluble ferment formed by certain bacteria, which, however, yield the ferment from the body of their cells only after they have been killed by alcohol.

Many different bacteria possess this property, especially Bacterium ureæ and Micrococcus ureæ, which are found abundantly in urines undergoing alkaline fermentation.
