Century Dictionary and Cyclopedia

  1. n. The act or process of putrefying; the decomposition of animal and vegetable substances, attended by the evolution of fetid gases. Putrefaction is at present believed to be a result of the activity of organisms of the simplest form — the Schizomycetes. It can therefore take place only when the conditions are favorable for the life and growth of these organisms. A temperature of from 60° to 80° F., a moderate degree of humidity, and limited access of air are the conditions most favorable to putrefaction. Extremes of heat and cold, salt, sugar, vinegar, carbolic acid, corrosive sublimate, and other antiseptics prevent putrefaction by destroying or rendering inactive the organisms which induce it. The chemical changes in a putrefying body are most complex. From proteid bodies are formed leucin, tyrosin, a considerable number of alkaloids, the ptomaïnes, compound ammonias, hydrogen sulphid, and many other solid and gaseous products. See fermentation, and germ theory (under germ).
  2. n. Putrefied matter.
