PRESENTATION OUTLINE

LOUIS PASTEUR

He took two flasks and filled them with broth from soup.
He had one that was straight necked and had one that was 'S' shaped.
He boiled the broth for a couple days and left it at room temperature.
He then saw that the one with a straight neck was cloudy and the one in a 'S' form was normal.

WHAT HE CONCLUDED

Pasteur said that if spontaneous generation had been a real phenomenon the broth in the curved-neck flask would have eventually become reinfected because the germs would have generated.
But the curved-neck flask never became infected, indicating that the germs could only come from other germs.

An electric current was dish discharged through a condenser to correct any liquid products.
This resulted in the creation of coacervates.
