Notable contributors to the theory include Justus Von Liebig and Louis Pasteur, the latter of whom developed a purely microbial basis for the fermentation process based on his experiments. Pasteur's work on fermentation later led to his development of the germ theory of disease, which put the concept of spontaneous generation to rest. [1]

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.
The contents of the flask thus remain free of microbes, a property showcased by French microbiologist Louis Pasteur in nineteenth century experiments used to support germ theory as the cause of fermentation over spontaneous generation from bad air .

Despite his other successes, Louis Pasteur (1822–1895) was unable to find a causative agent for rabies and speculated about a pathogen too small to be detected using a microscope. [1] In 1884, the French microbiologist Charles Chamberland (1851–1931) invented a filter – known today as the Chamberland filter – that had pores smaller than ...
More generally, in the medical literature, the Pasteur effect refers to how the cellular presence of oxygen causes in cells a decrease in the rate of glycolysis and also a suppression of lactate accumulation. The effect occurs in animal tissues, as well as in microorganisms belonging to the fungal kingdom. [2] [3]
Jean Baptiste Pasteur, the only son of Louis and Marie Pasteur, was a soldier in the Franco-Prussian War. The tone set by this war contributed to the rivalry between Koch and Pasteur. [ 1 ] The "German Problem", as Germany increasingly gained scientific, technological, and industrial dominance, fed tensions among European nations. [ 3 ]
1864 – Louis Pasteur disproved the spontaneous generation of cellular life. 1865 – Gregor Mendel demonstrated in pea plants that inheritance follows definite rules. The Principle of Segregation states that each organism has two genes per trait, which segregate when the organism makes eggs or sperm.
