The Theory
of Spontaneous Generation was finally disproved by the great French Chemist
Louis Pasteur. The theory states that life forms are spontaneously created in
organic matter. He disproved this theory by showing that the air is full of
microorganisms. He did this by letting air pass through gun cotton filters that
were dissolved with a mixture of ether and alcohol. He observed that the
particles were released and settled at the bottom part of the liquid.
Through
this observation he revealed numerous microbes that resembled the types of bacteria
found in petri dishes. This observation led him to disprove the theory because he
concluded that bacteria present in the air would likely land on and contaminate
any material exposed to it.
