[5] [6] From the two experiments, Pasteur concluded that the atmospheric dust carried germs responsible for the 'spontaneous generation' in his broths. [6] Thus, Pasteur's work provided proof that the emergent growth of bacteria in nutrient broths is caused by biogenesis rather than some form of spontaneous generation.
Pasteur's claim followed the German physician Rudolf Virchow's doctrine Omnis cellula e cellula ("all cells from cells"), [49] itself derived from the work of Robert Remak. [50] [38] After Pasteur's 1859 experiment, the term "spontaneous generation" fell out of favor. Experimentalists used a variety of terms for the study of the origin of life ...
Pasteur decided to partake in this competition to combat Pouchet's support of spontaneous generation. He designed an experiment to deny the notion of spontaneous generation. He thought that if spontaneous generation were true in which air itself could cause generation, then all sterile swan neck flasks that were later exposed to air would ...

These were some of the most important experiments disproving the theory of spontaneous generation. Pasteur gave a series of five presentations of his findings before the French Academy of Sciences in 1881, which were published in 1882 as Mémoire Sur les corpuscules organisés qui existent dans l'atmosphère: Examen de la doctrine des ...
Nothing grew in the broths in the course of Pasteur's experiment. This meant that the living organisms that grew in such broths came from outside, as spores on dust, rather than spontaneously generated within the broth. Thus, Pasteur refuted the theory of spontaneous generation and supported the germ theory of disease. [17]
Louis Pasteur uses S-shaped flasks to prevent spores from contaminating broth. This disproves the theory of Spontaneous generation (1861) extending the rancid meat experiment of Francesco Redi (1668) to the micro scale.
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 .
