Introduction In this experiment‚ the gram negative bacterium Escherichia coli is being subjected to various environmental factors that affect the rate of growth. These factors scrutinized were the different types of nutrients‚ the intensity of aeration‚ or the temperature at which it was stored. The purpose of this lab is to determine which factor affects the Escherichia coli the greatest. It is known that these abiotic factors affect the rate of growth the greatest if they remain at the correct
