1. The foam, or troth (top yeast), or the sediment (bottom yeast), of
beer or other in fermentation, which contains the yeast plant or its
spores, and under certain conditions produces fermentation in
saccharine or farinaceous substances; a preparation used for raising
dough for bread or cakes, and making it light and puffy; barm;

2. Spume, or foam, of water.
They melt thy yeast of waves, which mar Alike the Armada's pride, or
spoils of Trafalgar. Byron.
Definition: A form of fungus which grows as indvidual rounded cells, rather
than in a mycelium, and reproduces by budding; esp. members of the
orders Endomycetales and Moniliales. Some fungi may grow both as a
yeast or as a mycelium, depending on the conditions of growth. Yeast
cake, a mealy cake impregnated with the live germs of the yeast
plant, and used as a conveniently transportable substitute for yeast.
– Yeast plant (Bot.), the vegetable organism, or fungus, of which
beer yeast consists. The yeast plant is composed of simple cells, or
granules, about one three-thousandth of an inch in diameter, often
united into filaments which reproduce by budding, and under certain
circumstances by the formation of spores. The name is extended to
other ferments of the same genus. See Saccharomyces.
– Yeast powder, a baling powder, -- used instead of yeast in
leavening bread.
