-
Best known for his work on the improvement of the microscope and for his contributions towards the establishment of microbiology.
-
He did experiments with gravy and later, tainted wheat, in containers. This was in order to experiment with spontaneous generation.
-
Interpreting digestion, a process of chemical solution, and helped disprove the concept of spontaneous generation.
-
An English scientist from Berkeley, Gloucestershire, he was the founder of smallpox vaccine.
-
development of cell theory, discovered Schwann cells in the peripheral nervous system, discovered the organic nature of yeast, and invented the term metabolism.

-
Pasteurization is the process of heating liquids for the purpose of destroying bacteria, protozoa, molds, and yeasts.
-
He inoculated chickens with the attenuated form and demonstrated that the chickens were resistant to the fully virulent strain. Pasteur directed all his experimental work toward the problem of immunization.
-
By applying Louis Pasteur's advances in microbiology, he promoted sterile surgery. He successfully introduced carbolic acid to sterilise surgical instruments and to clean wounds, which led to a reduction in post-operative infections and made surgery safer for patients
-
Air allowed to enter flask but only after passing through a heated tube or sterile wool
-
Founder of modern bacteriology, known for his role in identifying the specific causative agents of tuberculosis, cholera, and anthrax.
-
He developed the Chamberland filter, a device that made use of an unglazed porcelain bar.The filter had pores that were smaller than bacteria, thus making it possible to pass a solution containing bacteria through the filter, and having the bacteria completely removed from the solution.
-
The Avery–MacLeod–McCarty experiment was an experimental demonstration showing that DNA is the substance that causes bacterial transformation.
-
He studied epidemic diseases and attributed their spread to tiny particles that could transmit infection by direct or indirect contact or even without contact over long distances.
