Summary Introduction
Louis Pasteur is a French microbiologist, who having renowned discoveries of microbial fermentation, pasteurization, and vaccination. Pasteur is the responsible person for disproving the spontaneous generation. He conducted many experiments related to microbial contaminations. Pasteur’s vaccine discovery reduces the mortality rate of rabies and anthrax. He proposed germ theory to understand about the diseases caused by microbes.

Pasteur’s work with the swan neck flasks was only of importance to the food industry; his work occurred long before anyone, including Pasteur, had any awareness that diseases could be caused by microscopic agents. The swan necked flasks were used to prove that life could only arise from pre-existing cells.arrow_forward
