What 3 things did Louis Pasteur discover?
Louis Pasteur ForMemRS (/ˈluːi pæˈstɜːr/, French: [lwi pastœʁ]; 27 December 1822 – 28 September 1895) was a French chemist and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization, the latter of which was named after him.
What was the impact of pasteurization?
When performed properly, pasteurization destroys the pathogenic bacteria, yeast, molds, and almost all other nonpathogenic bacteria that may be associated with unpasteurized milk. Additionally, pasteurization inactivates most enzymes related to milk spoilage.

Louis Pasteur, a qualified chemist, was behind the most important scientific revolutions of the 19th century in the fields of biology, agriculture, medicine and hygiene. Beginning his research on crystallography, he soon embarked on a journey filled with discoveries which led him to develop the rabies vaccine.

Germ theory of fermentation which helped us understand how our food gets infected or spoiled.
Why do we use the Pasteur effect?
We use the Pasteur effect and Pasteurization everyday in our lives because this is how we are able to drink good milk.
What did Pasteur do to the wine industry?
Figuring prominently in early rounds of these debates were various applications of his pasteurization process, which he originally invented and patented (in 1865) to fight the “diseases” of wine. He realized that these were caused by unwanted microorganisms that could be destroyed by heating wine to a temperature between 60° and 100°C. The process was later extended to all sorts of other spoilable substances, such as milk.
What was Pasteur's research campaign?
In his research campaign against disease Pasteur first worked on expanding what was known about anthrax, but his attention was quickly drawn to fowl cholera. This investigation led to his discovery of how to make vaccines by attenuating, or weakening, the microbe involved.
How did Pasteur return chickens to virulence?
Pasteur usually “refreshed” the laboratory cultures he was studying—in this case, fowl cholera—every few days; that is, he returned them to virulence by reintroducing them into laboratory chickens with the resulting onslaught of disease and the birds’ death.
What happened to Pasteur in 1868?
In 1868, in the middle of his silkworm studies, he suffered a stroke that partially paralyzed his left side. Soon thereafter, in 1870, France suffered a humiliating defeat at the hands of the Prussians, and Emperor Louis-Napoléon was overthrown. Nevertheless, Pasteur successfully concluded with the new government negotiations he had begun with the emperor. The government agreed to build a new laboratory for him, to relieve him of administrative and teaching duties, and to grant him a pension and a special recompense in order to free his energies for studies of diseases.
Why did Pasteur want to move into the more difficult area of human disease?
Pasteur then wanted to move into the more difficult area of human disease, in which ethical concerns weighed more heavily. He looked for a disease that afflicts both animals and humans so that most of his experiments could be done on animals, although here too he had strong reservations.
What did the Germ Theory believe?
He and a minority of other scientists believed that diseases arose from the activities of microorganisms —germ theory. Opponents believed that diseases, particularly major killer diseases, arose in the first instance from a weakness or imbalance in the internal state and quality of the afflicted individual.
Why did the government grant the scientist a pension?
The government agreed to build a new laboratory for him, to relieve him of administrative and teaching duties, and to grant him a pension and a special recompense in order to free his energies for studies of diseases.
