With science there are many branches, one of these branches is Microbiology and within this specific branch theories have been created. It may not be obvious theories are ever evolving and go through changes and previous theories are falsified and new ones emerge. For instance, the theory of biogenesis was first introduced by a man named Rudolph Virchow, who eagerly challenged the current theory of spontaneous generation at the time. Spontaneous generation theory was the thought that some forms of life could actually be spontaneously created out of thin air. An example of spontaneous generation was that flies could develop from manure for no reason other than just because that is how it was. Virchow knew this could not be true and …show more content…
This ultimately showed that the sealed flasks after boiling contained no contamination and however the open flasks did possess contaminants. Another experiment involved an S shaped flask that Pasteur designed himself. Over months it showed that air did not contaminate the boiled beef broth and that the S curve in the flask trapped any potential microorganisms that may have been airborne. Therefore, proving that air in fact contains microorganisms which could actually contaminate solutions that were previously sterile and it showed that there can be life on non-living materials. This heating procedure in his experiments also lead to what is respectively entitled pasteurization which is more or less heating solutions (e.g., beer, wine, milk) to kill bacteria that may be causing spoilage.
But a man named Robert Koch who was actually a rival of Louis Pasteur’s at the time in the race to find a cure for a disease known as Anthrax, attempted to use specific microorganisms with actual diseases. These experiments that Pasteur and Koch produced are said to be the pivotal structure of what produced the germ theory of disease, which is the thought that certain diseases result from specific germs. It is interesting to note that the series of steps used by Koch later became known as Koch’s postulates, which are still considered to be a reliable way to categorize specific
