The French Louis Pasteur (1822–1895) and German Robert Koch (1843–1910) are the two greatest figures in medical microbiology and in establishing acceptance of the germ theory of disease (germ theory). [1] In 1882, fueled by national rivalry and a language barrier, the tension between Pasteur and the younger Koch erupted into an acute ...
Pasteur was then asked by Napoleon III to study French wineries because a large portion of French wine was contaminated. [45] Pasteur believed that heating the wine could destroy the microorganisms which had contaminated it. This process became known as pasteurization.

Koch's postulates (/ k ɒ x / KOKH) [2] are four criteria designed to establish a causal relationship between a microbe and a disease. The postulates were formulated by Robert Koch and Friedrich Loeffler in 1884, based on earlier concepts described by Jakob Henle , and the statements were refined and published by Koch in 1890. [ 3 ]
Heinrich Hermann Robert Koch (/ k ɒ x / KOKH; [1] [2] German: [ˈʁoːbɛʁt ˈkɔx] ⓘ; 11 December 1843 – 27 May 1910) was a German physician and microbiologist.As the discoverer of the specific causative agents of deadly infectious diseases including tuberculosis, cholera and anthrax, he is regarded as one of the main founders of modern bacteriology.
Louis Pasteur and Robert Koch were contemporaries of Cohn, and are often considered to be the fathers of modern microbiology [16] and medical microbiology, respectively. [18] Pasteur is most famous for his series of experiments designed to disprove the then widely held theory of spontaneous generation , thereby solidifying microbiology's ...
The first culture media was liquid media, designed by Louis Pasteur in 1860. [2] This was used in the laboratory until Robert Koch's development of solid media in 1881. [3] Koch's method of using a flat plate for his solid media was replaced by Julius Richard Petri's round box in 1887. [2]
The liquid culture pasteur developed allowed for the visulization of promoting or inhibiting growth of specific bacteria. This same technique is utilized today through various mediums like Mannitol salt agar, a solid medium. Solid cultures were developed in 1881 when Robert Koch solidified the liquid media through the addition of agar [2]
In an 1857 experiment, Pasteur was able to isolate microorganisms present in lactic acid ferment after the chemical process had taken place. [9] Pasteur then cultivated the microorganisms in a culture with his laboratory. He was then able to accelerate the lactic acid fermentation process in fresh milk by administering the cultivated sample to ...
