Biography of Louis Pasteur

This process for use with beer and take out soon spread worldwide (Hyperlab, 2004).

At this time, there was in time an ongoing debate over spontaneous generation (Cohn, 1996). Pasteur lay out an end to this argument with experiments to show that contamination from glowborne particles resulted in the unrest of wine-colored. Placing wine samples in swan- peted flasks, he exposed their wine contents to air collected at different elevations, from sea level to mountain tops. The higher the elevation, the less dust in the air, and the less fermentation it produced. Dust particles were trapped in the neck of the flask, and the entering air did not produce fermentation, showing that air itself did not generate growth of microorganisms, but if the flasks were tilted so that the wine touched the dust trapped in the necks, fermentation occurred (Cohn, 1999; Klyce, 2004). This demonstrated that the microorganisms responsible for fermentation were contained in the dust particles in the air. At the same time, Pasteur discovered that "fermentation is the consequence of life story without air," discovering anaerobic life (Hyperlab, 2004).

While helping the brewer, Pasteur was asked to investigate a malady which was destroying silk worms and dev

Anthrax was decimating the sheep labor in France, and though the anthrax bacillus had been isolated from late(prenominal) sheep, no one was fully convinced that it was the cause of the complaint and not something in the culture speciality (Cohn, 1996). Pasteur took a range of blood from an infected sheep, diluted it in 50 ml of sterile culture and grew the bacterium, then repeated the process speed of light times until none of the original culture medium was left.

This put up culture was just as effective at producing the infirmity as the original, proving that it was the anthrax bacillus and not the culture medium which caused the disease. Pasteur also discovered that the disease was spread by sheep universe exposed to the carcasses of dead infected sheep, buried in the fields, and the spores existence brought to the surface by earthworms.

Pasteur's development of the germ theory of disease and the use of vaccines to prevent these diseases were his major accomplishments (Cohn, 1996; Rhee, 2004). His experiments with the fermentation of wine take others to realize that diseases were due to microorganisms. Lister in England began to sterilize his instruments, and bandages were sprayed with phenol solutions in his operations to reduce infections after surgery. However, the medical shaping still refused to believe that important diseases like cholera, diphtheria, scarlet fever, vaginal birth fever, syphilis and smallpox were caused by microorganisms. Pasteur tried to stress the wideness of washing hands, sterilizing instruments, and only using clean dressings and bandages to doctors and
