By actual experimentation, the great French scientist Louis Pasteur disproved this false theory of spontaneous generation.
Abiogenesis is not the same as spontaneous generation! Spontaneous generation actually posits that full born organisms come from miasma and the like. Abiogenesis posits by hypothesis that life is of simpler organic constituents.
Pasteur then entered a contest sponsored by The French Academy of Sciences to disprove the theory of spontaneous generation. Similar to Spallanzani's experiments, Pasteur experiment, pictured in Figure 1-6, used heat to kill the microbes, but left the end of the flask open to the air. In a simple, but brilliant modification, the neck of the flask was heated to melting and drawn out into a long S-shaped curve, preventing the dust particles and their load of microbes from ever reaching the flask. After prolonged incubation the flasks remained free of life and ended the debate for most scientists.

Abiogensis is not the same as spontaneous generation.
Pasteur's law only disproved the (then current) idea that life forms such as mice, maggots, and bacteria can appear fully formed. It does not say that very primitive life cannot form from increasingly complex molecules.
Do you mean abiogenesis? Biogenesis is just cell theory and cells come from cells.
Pasteur did not disprove biogenesis or abiogenesis. He disproved spontaneous generation which is a very different thing.
Louis broiled broth for 15 min. He then let it sit for one year in a swan neck flask. He noticed that some dust had accumulated in the top part of the flask. So he took a sample, form the broth inside the flask. He noticed that nothing was inside of growing in it. Then he broke the neck of the flask making it easier for the air containing dust to come into the flask. He left it there for one day. The next day the broth was cloudy. Which proved that there were microorganisms in the air and it is not any vital force in the air that grows things.
He didn't. He disproved spontaneous generation.
Louis Pasteur disproved spontaneous generation by using swan neck flask for experiments. He also figured germs would get stuck in swan neck and nothing would grow.
Louis pasteur reject abiogenesis theory and give biogenesis theory which state that life exist from pre existing life. He prove it by one of his famous experiment of S shape funnel broth experiment
Louis Pasteur discovered the germ theory of disease and invented pasteurization in 1848.
Louis Pasteur contributes the germ theory of the infectious diseases.
i dont know how about you answer that and go make me a sandwich... thanks (:

Redi and Pasteur helped to disprove spontaneous generation.
Francesco Redi, in 1668, showed that abiogenesis of maggots did not occur, and further experiments by Lazzaro Spallanzani (1768) and Louis Pasteur (1861) showed that many of the lifeforms thought "created" were those already invisibly present in the air or in other materials.
Louis Pasteur developed the germ theory for disease!
Louis Pasteur was able to convince others of his germ theory by performing extensive experiments. Through these experiments, he was able to disprove spontaneous generation and prove biogenesis.
The Germ theory of disease, developed in the 1860s and 1870s by Louis Pasteur

Spontaneous generation is known as abiogenesis, which is life arising from non-living material. However, this was refuted by Louis Pasteur who proved that living things arise from other living things.
