Louis Pasteur (1822-1895) is one of the founders of medical biology, along with Robert Koch. He discovered vaccines against rabies, fowl cholera and antrax. He proved the Spontaneous Theory to be wrong. He also discovered the method of preserving food by means of pasteurization
There were few discoveries in his life............
Originsbottle. The only way for microorganisms to enter there and populate was through a tube. But the tube had too many curves to forbid them from entering. If a hole was made to this tube, the microorganism could enter and populate into the rotten matter. After that, Spontaneous Generation Theory could be proved to be false Edit
He also help to improve the mechanisms of fermentation in the making of beer. He invented the process of pasteurization to clean them from microbes. Pasteurization is a process in which the solution is heated to certain degress and then rapidly cooled. That way, the few microbes that survived to heating could not survive the fast cooling afterwards. Thus, he could use this process to destroy viruses, bacteria and other harmful microorganisms.
