The technique of serial passage has been around since the 1800s. In particular, Louis Pasteur's work with the rabies vaccine in the late 1800s exemplifies this method. [7] Pasteur created several vaccines over the course of his lifetime. His work prior to rabies involved attenuation of pathogens, but not through serial passage.
Louis Pasteur ForMemRS (/ ˈ l uː i p æ ˈ s t ɜːr /, French: [lwi pastœʁ] ⓘ; 27 December 1822 – 28 September 1895) was a French chemist, pharmacist, and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation, and pasteurization, the last of which was named after him.
Louis Pasteur was a French chemist who discovered chirality while studying crystals. This discovery became the basis for a new form of chemistry called stereochemistry . [ 49 ] [ 50 ] While Pasteur was studying paratartrate crystals in 1857, he discovered that his calcium paratartaric acid solutions were growing fungi.

One of the chemical processes that Pasteur studied was the fermentation of sugar into lactic acid, as occurs in the souring of milk. 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 ...
Acetobacter aceti, a Gram-negative bacterium that moves using its peritrichous flagella, was discovered when Louis Pasteur proved it to be the cause of conversion of ethanol to acetic acid in 1864. Today, A. aceti is recognized as a species within the genus Acetobacter, belonging to the family Acetobacteraceae in the class Alphaproteobacteria. [1]
This taxonomical group of bacteria was named after Louis Pasteur, a name formally accepted in 1981. The designation was conceived to accommodate a collection of gram-negative organisms currently representing 34 genera and 105 species, described as “specialized commensals, primarily and potential pathogens of vertebrates–mainly mammals and ...
Major contributions to the science of microbiology (as a discipline in its modern sense) have spanned the time from the mid-17th century month by month to the present day. The following is a list of notable microbiologists who have made significant contributions to the study of microorganisms .
