Title
The Effect of Different Music Genres on the Growth of the Bacteria Serratia marcescens
Introduction
Exploring the question of does music affect bacterial growth requires much research. The purpose of answering this question is to figure out how to slow down bacterial growth by music. Also, if needed, the purpose is to figure out how to speed up bacterial growth through music. The hypothesis is that if the bacteria Serratia marcescens is put together with country music, the bacterial colonies will be much larger when compared to classical music and no music. The independent variable is the different music genres. The dependent variable is the growth of the bacteria. Some constants …show more content…
This means that to measure bacteria a person will have to count the cell numbers not measure the size of the cell. According to Frank O’Mahony, bacterial growth is affected mostly by temperature, nutrient, water supply, oxygen supply, and the acidity of the medium, which leads to the question of could vibrations from music affect the bacterial growth. O’Mahony said that bacteria cannot live without nutrients and water, which means that the bacteria will need nutrients and water throughout the testing process. (O’Mahony, 1988)
A sewage plant near Berlin started to play Mozart to the bacteria to drive down the cost of running the sewage plant. The founder of the sewage plant figured that if humans like Mozart, then bacteria must like Mozart’s music. However, scientists know that the sonic waves of the composition mixed with the addition of oxygen lead to a better result from the bacteria. This led to huge amount of money saved, which is a reason how this experiment could better life today. This idea showed that there might be an increase of bacterial growth when it is combined with classical music. (Spiegel Online, …show more content…
For example, Chu, Joseph, and Lee concluded that music does not increase bacterial growth, but rather decreases it, which was discovered in this experiment. (Chu, Joseph, and Lee, 2012) Some errors were that the music playing could have been not exactly the same, the agar that was poured at the beginning of the experiment could have been poured unequally, and the bacteria could have been distributed unequally. Some improvements that could have been done to the experiment were a longer growing time, having more varieties to the music, and measuring the amount of agar into each petri plates.
Both table one and figure one have shown that no music grows the most bacteria, country music minimizes the growth of bacteria a little bit, and classical music stunts the growth of bacteria. These results could be applied to places where bacteria should not be. People could play classical music to stunt the growth of bacteria. The hypothesis of that country music will produce more bacterial colonies than no music and classical music was disproven. That was due to the fact that no music had the most bacteria, country had the second largest, and classical music had the
