The soil sample was taken taken from a local park located in SugarLand. A 8-10 feet hole was dug into the ground and a mixture of wet and dry soil was collected in put into the soil collection tube. Over the course of 5 weeks it was noted that the Sulfur Selective Media with the Paraoxon was the best at showing pesticide degradation in bacteria. It was noted in week 4 and week 5 of the experiment that the the SSM+PX tube turned orange then, burnt orange. In the agar plate, it was noted that the PX resulted in two types of bacteria, the larger bacteria around the outside was able to hydrolyze and the bacteria towards the center was only able to tolerate the paraoxon.
