How did work of louis pasteur help improve the quality of life for people during the industrial revolution?

It led to new ways of fighting diseases.

Explanation:

Louis Pasteur was a French chemist and microbiologist who was one of the most important founders of medical microbiology. He pioneered the study of molecular asymmetry; discovered that microorganisms cause fermentation and disease; originated the process of pasteurization; saved the beer, wine, and silk industries in France; and developed vaccines against anthrax and rabies.

It led to new ways to fight disease.

Explanation:

Louis Pasteur was a French biologist and chemist who made enormous contributions to germ theory, to prevention of food spoilage, and to the control of disease.

Louis Pasteur discovered that microbes were responsible for souring alcohol and came up with the process of PASTEURIZATION, where bacteria is destroyed by heating beverages and then allowing them to cool.

Pasteur developed practices are still used today for preventing disease in silkworm eggs.

In 1881, he helped develop a vaccine for anthrax, which was used successfully in sheep, goats and cows. Then, in 1885, while studying rabies, Pasteur tested his first human vaccine. Pasteur produced the vaccine by attenuating the virus in rabbits and subsequently harvesting it from their spinal cords. Using his germ theory of disease, pasteur developed vaccines for chicken cholera, anthrax, and rabies.
