Reversibility of Ferment Action

Studies in Ferment Action

1. A single intravenous injection into dogs of a sufficient number of freshly washed typhoid bacteria produces the symptoms and pathology that characterize anaphylaxis in these animals. 2. These effects are not produced by the coagulable protein-free filtrate from a fresh emulsion, while a similar filtrate from an emulsion digested with leucoprotease is very potent, the toxic portion of the bac...

Studies on Ferment Action

1. Erythrocytes have definite lipoidal constituents and lipoidal combinations peculiar to the species. 2. Certain lipoids and lipoidal combinations act as specific antigens. 3. The increase in serum lipase which occurs upon immunization of animals to foreign red cells is, at least in part, specific. 4. This specific lipase plays, no doubt, an important part in specific serum hemolyses.

The Reversibility of the Action of Urease of Soy Bean.

Ferment in the family tree.

In 1953, botanist Jonathan D. Sauer suggested that our initial motivation to cultivate cereals was not for flour or bread, but for beer (1). The implications of this idea— that a preference for dietary ethanol, or alcohol, sparked the Neolithic Revolution (2)—are profound. No stage of human evolution has left a larger global footprint than the domestication of plants, animals, and landscapes (3...

Ferment-inhibiting Substances in Tubercle Bacilli

1. Tubercle bacilli contain unsaturated fatty acids which, when saponified, have the property of inhibiting the action of trypsin and leucoprotease. 2. In proportion to their iodin value these soaps are more active as inhibiting agents than the soaps prepared from linseed, olive, and cod-liver oils. 3. The activity of the soaps is dependent on the presence of unsaturated carbon bonds. 4. Satura...
