A chemical phenomenon in which an organic molecule splits into simpler substances

Usage examples of ferment.

It may be well to premise for the sake of any reader who knows nothing about the digestion of albuminous compounds by animals that this is effected by means of a ferment, pepsin, together with weak hydrochloric acid, though almost any acid will serve.

Even if I had tried no other experiments than these, they would have almost sufficed to prove that the glands of Drosera secrete some ferment analogous to pepsin, which in presence of an acid gives to the secretion its power of dissolving albuminous compounds.

In the far East the calamus is still used, the best being gathered in the month of March, near Aurac, on the Persian Gulf, and still prepared after the old method of immersing them for about six months in fermenting manure which coats them with a sort of dark varnish and the darker their color the more they are prized.

At last Tooney Blake hit upon Cyfer, a compression of Cytology Ferment.

Now, it is a remarkable fact, which affords additional and important evidence, that the ferment of Drosera is closely similar to or identical with pepsin, that none of these same substances are, as far as it is known, digested by the gastric juice of animals, though some of them are acted on by the other secretions of the alimentary canal.

From all these, perhaps, and from other monsters likewise--goblin shapes evolved by Nature as destroyers, as equilibrists, as counterchecks to that prodigious fecundity, which, unhindered, would thicken the deep into one measureless and waveless ferment of being.

Gruad attempts to speak to Yog Sothoth, but the possession has apparently passed, and the other members of the Unbroken Circle praise a new beverage that Evoe has prepared, made of the fermented juice of grapes.

Swedish peasantry prepare from the fresh berries a fermented beverage, which they drink cold, and an extract, which they eat with their bread for breakfast as we do butter.

Again, a wine can be brewed from the fermented juice, which is excellent against scurvy because of its salts of potash--the citrate and malate.

But it also shows that when the manure has been fermented for six months, and is then turned and left exposed to the rain of spring and summer, the loss is very considerable.

The heap of manure in the shed probably fermented more rapidly than the heap out of doors, and there was not water enough in the manure to retain the carbonate of ammonia, or to favor the production of organic acids.

I get my winter-made manure fermented and in good condition, and yet have it ready for spring crops.

Or, if the manure was first fermented, so that the particles of matter would be more or less decomposed and broken up fine, the rain would wash out a large amount of soluble matter, and prove much more injurious than if the manure was fresh and unfermented.

I allow myself the pleasure of thinking that I am causing some of my readers a little surprise when I tell them that cacao is fermented, and that the fermentation produces alcohol.

It is commonly stated that during fermentation there is generated theobromine, the alkaloid which gives cacao its stimulating properties, but the estimation of theobromine in fermented and unfermented beans does not support this.
