if
food is allowed to stand for some time, it
putrefies. when
the putrefied material
is examined microscopically, it is found
to be teeming with bacteria. where do
these bacteria come
from , since they
are not seen in fresh food? even until the
mid-nineteenth century, many people
believed that such
microorganisms
originated by spontaneous generation, a
hypothetical process by which living
organisms develop from
nonliving
matter.
the most powerful
opponent of the theory of spontaneous
generation was the french chemist and
microbiologist louis
pasteur(1822-1895).pasteur showed that
structures present in
air closely
resemble the. microorganisms seen in putrefying
materials .he did this by passing air
through guncotton filters,
the fibers
of which stop solid particles. after the guncotton
was
dissolved in a mixture of alcohol
and ether, the particles that it
had
trapped fell to the bottom of the liquid and were
examined
on a microscope slide .pasteur
found that in ordinary air these
exists
a variety of solid structures ranging in size from
0.01
mm to more than 1.0 mm .many of
these bodies resembled the
reproductive
structures of common molds, single-celled animals,
and
various other microbial cells. as
many as 20 to 30 of them were
found in
fifteen liters of ordinary air ,and they could not
be
distinguished from the organisms
found in much larger
numbers in
putrefying materials .pasteur concluded that the
organisms found in putrefying materials
originated from the
organized bodies
present in the air. he postulated that these
bodies are constantly being deposited
on all objects.
pasteur
showed that if a nutrient solution was sealed in a
glass flask and heated to boiling to
destroy all the living
organisms
contaminating it, it never putrefied. the
proponents
of spontaneous generation
declared that fresh air was
necessary
for spontaneous generation and that the air inside
the sealed flask was affected in some
way by heating so that it
would no
longer support spontaneous generation. pasteur
constructed a swan-necked flask in
which putrefying materials
could he
heated to boiling, but air could reenter. the
bends in
the neck prevented
microorganisms from getting in the flask..
material sterilized in such a flask did
not putrefy.
