There was rigorous attention to every detail. Flasks opened in the paris streets grew organisms abundantly, those opened in the high mountains remained sterile with rare exception. To his own satisfaction, and that of the lAcadÃmie des Sciences, pasteur demonstrated that microorganisms appeared in flasks of sterile culture medium only when contaminated by exposure to contaminated air from the outside, and never by spontaneous generation. In 1861 he summarized his findings in the essay sur les corpuscules organisÃs qui existent dans latmosphère. Examen de la doctrine des gÃnÃrations spontanÃes. (On the organized bodies which exist in the air.

Examination of the doctrine of spontaneous generation.). Pasteur considered the matter closed. Nevertheless, the dispute dragged on and we can detect his exasperation in the tone of his lecture at the sorbonne in 1864 when he outlined the history of the controversy and concluded by saying: Gentlemen, i could point to that liquid (in the flask. And I wait, i watch, i question it, begging it to recommence for me the beautiful spectacle of the first creation. But it is dumb, dumb since these experiments were begun several years ago; it is dumb because i have kept it from the only thing man cannot produce, from the germs which float in the air, from Life, for Life is a germ and. Never will the doctrine of spontaneous generation recover from the mortal blow of this simple experiment. No, there is now no circumstance known in which it can be affirmed that microscopic beings came into the world without germs, without parents similar to themselves. Those who affirm it have been duped by illusions, by ill-conducted experiments, spoilt by errors that they either did not perceive or did not know how to avoid. Meanwhile, pouchet continued to generate life in his sterile cultures.

According to this theory, the ghostwriter microorganisms associated with fermentation were the product and not the cause of the process. The ancient and hardy doctrine of spontaneous generation, rooted in the speculations of the Greek philosopher Aristotle of the fourth century. C., was strongly supported by fãlix Archimède pouchet (1800-1872 director of the museum of Natural History in rouen, a french city northeast of Paris. In a paper read before the paris Academy of Sciences in 1858 he claimed to be able to produce spontaneous generation at will in a sterile culture medium. Pasteur, unerring in his sense that this stubborn doctrine required the coup de grace as only he could administer it, was unwilling to let pouchets claim go unchallenged. Therefore, he began an extensive series of meticulous experiments in 1859, the year of Darwins publication of the Origin of Species and the year that saw the opening of the first medical school on the pacific coast by Elias cooper. Pasteurs experiments took him from the crowded streets of Paris to the Alps, gathering samples of air in glass flasks containing sterile culture medium.

alcoholic fermentation, he went on to disprove the theory by demonstrating that yeast is the living agent of the process. He reported his findings in a mãmoire sur la fermentation appelÃe lactique (Memoir on the fermentation of lactic acid) in 1857, and a mãmoire sur la fermentation alcoholique (Memoir on the fermentation of alcohol) in 1860. Pasteurs experiments proved conclusively that fermentation is caused by microorganisms. In so doing, he provided a biological explanation for a phenomenon generally accepted as a chemical reaction. Furthermore, he established that specific microorganisms are responsible for specific biological processes and, by inference, that specific germs may be the agents of specific diseases. While pasteur thus laid the foundation for the germ theory of disease, validation of the theory awaited the test of clinical application soon to be undertaken by the British surgeon, joseph Lister. Doctrine of Spontaneous Generation, pasteur knew that his concept of biological activity by microorganisms was incompatible with the doctrine of spontaneous generation that still had many adherents. In his day the belief persisted that microscopic life forms could be spontaneously generated in putrefying organic material.

Fortunately for posterity he decided to go. Bigos distillery and have a look at his vats. He found that, part of the time and for no apparent reason, the alcoholic fermentation process for which yeast was the ferment began to produce lactic thesis acid, an acid usually obtained from sour milk. Pasteur decided that there were in fact two kinds of fermentation, each independent of the other, going on. Bigos vats: alcoholic fermentation due to yeast and lactic acid fermentation due to the lactic acid bacillus. When the alcoholic fermentation turned sour it was due to the production of lactic acid by a contaminant, the lactic acid bacillus. Pasteur discovered and isolated the bacillus, and believed that the air was the source of the contamination.
