What did Pasteur believe?

5 of 10

Pasteur believed that germs in the air may be the cause of the beer 'going off'. This was an unusual theory as, at the time, people believed that germs were a product of disease and decay, rather than a cause of it.

What did Pasteur experiment with?

7 of 10

Pasteur experimented with the fermentation process and soon realised that the germs were being created during the process. He proved this through experimentation.

What did he do

He warmed water and allowed it to bubble into the bend of a connecting pipe. After cooling the pipe was broken and decay set into the water very quickly. Many doctors were still sceptical however. By 1867 though, Pasteur was able to demonstrate unequivocally that there was a link between germs, decay and disease.
