The samples that I had conducted research on were not selected for further testing, I had little/no organophosphate-degrading bacteria present in my sample. As seen in Figure 4-8, there was almost no color change in my samples to indicate the presence of bacteria able to break down the pesticides MP or Px in order to survive in the selective media. Without the color change indication of my sample, I am able to conclude that the place where I collected my soil sample has not been exposed to the harmful chemicals that causes certain bacteria to adapt and find a new way of finding nutrients by breaking down the pesticides/pollutants that it has available
