4. He was a French chemist and microbiologist. He is known for his discoveries of principles of vaccination, microbial fermentation, and pasteurization. He crushed the doctrine of spontaneous generation. Louis Pasteur in his laboratory

5. He reduced the mortality from puerperal fever . He created first vaccines for rabies and anthrax . His medical discoveries provided direct support for the germ theory of disease . He is best known for his invention of the technique of treating milk & wine by gentle heating to stop bacterial contamination, a process now called pasteurization.

6. Louis Pasteur experiment for crushing the doctrine of spontaneous generation

7. Pasteur also made significant discoveries in chemistry, most notably on the molecular basis for the asymmetry of certain crystals and racemization. He is known as the ‘Father of modern microbiology ’ .

8. 2. Robert Koch Born : 11 December , 1843 Died : 27 May, 1910 Country: Germany Known for : Discovery of bacteriology Koch’s postulates of germ theory, Isolation of anthrax, tuberculosis, and cholera

9. He was a German physician and pioneering microbiologist. He is best known for giving four postulates, now called Koch’s postulates .

10. He discovered the causative agent of anthrax – Bacillus anthracis . Koch determined the causative agent of cholera, isolating Vibrio cholerae . He reported the causative agent of tuberculosis – Mycobacterium tuberculosis . Bacillus anthracis Vibrio cholerae Mycobacterium tuberculosis

11. Koch received the Nobel Prize in physiology and medicine in 1905 . He is known as the ‘Father of bacteriology’.
