Louis Pasteur is best known for developing which heat-treatment process, along with contributing to the germ theory of disease?

Explanation

Louis Pasteur developed pasteurization, a heat-treatment process that kills harmful bacteria in liquids like milk and juice without significantly affecting flavor, helping prevent foodborne illness. He also made major contributions to establishing the germ theory of disease, the now widely accepted understanding that many diseases are caused by microorganisms rather than other previously believed causes. His work laid important groundwork for the later development of vaccines and modern microbiology. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
