TOPIC: CONTRIBUTIONS OF SCIENTISTS IN MICROBIOLOGY 

📌 POINTS TO PONDER

📍LOUIS PASTEUR (1822-95)

• Originally trained as a chemist
• His studies on fermentation led him to take interest in microorganisms
• His discoveries revolutionized medical practice, although he never studied medicine.
• Louis Pasteur is known as “Father of microbiology" because his contribution led to the development of microbiology as a separate scientific discipline.

💡CONTRIBUTION OF LOUIS PASTEUR :

🔹Coined the term microbiology: for the study of living organisms of microscopic size.

🔹Proposed germ theory of disease: putrefaction and fermentation was the result of microbial activity and that different types of fermentations were associated with different types of microorganisms (1857).

🔹Disapproved theory of spontaneous generation: He disapproved the theory of spontaneous generation in 1860-61.

🔹Developed sterilization techniques: Introduced sterilization techniques and developed the steam sterilizer, hot-air oven and autoclave in the course of these studies.
