Pasteurs 1862 experiment put to rest the notion that life evolves from nonlife in todays world. His experiments showed that microorganisms come only from other microorganisms and that a genuinely sterile solution remains lifeless indefinitely unless contaminated by living creatures.

It is argued that this 'popular' level of representation did not merely provide additional publicity for Pasteur's ideas. Rather, the nature and meaning of the experiment itself and of the related controversy on immunisation were substantially negotiated and shaped within the public arena.

This controversy continued till around the middle of the 19th century when Louis Pasteur the French organic chemist, showed that growth did not occur in infusions which had been heated but exposed to air provided the incoming air was treated to remove the microorganisms.
