The purpose of the research conducted was to determine the ability of the bacteria P.putida and P.fluorescens to break down medium density polyethylene in greater amounts than either one could break down alone. The research was conducted due to the growing amount of plastic left untouche din the status quo. The EPA estimated that about 32 million tons of plastic were generated in 2012 alone. Plastic, being naturally resistant to any chemical degradation, pollutes the environment and seriously threatens biodiversity in aquatic areas. The approach of using bacteria as a remediation method for the breakdown of plastic is becoming more and more prevalent; the focus lies on Pseudomonas putida, as a study conducted in 2009 showed P.putida's ability to break down o-chloronitrobenzene and use it as its sole source of carbon and nitrogen. This study could also be applied to P fluorescens. Therefore this study was conducted to determine the potential relationship between P.putida and P.fluorescens and their ability to break down plastic faster together than by themselves. Three experimental groups and one control group were set up in ten sterile test tubes. All test tubes were filled with 10 mL of a specific bacterial growth solution that contained 200 milligrams of medium density polyethylene as the main food source for bacteria; the first three contained 100% P.fluorescens, the second three contained 100% P.putida, and the final three contained 50% of each bacterium. The last one was a singular control with no bacteria. Results were measured first through turbidity via spectrophotometer, then the solution was filtered to remove bacteria and the remaining plastic was massed after being dried in an oven. The tube with 50% of each bacteria degraded the most plastic (0.0903 grams) in three weeks, with the other two types of bacteria degrading less. The ANOVA test determined that the statistical difference between all three groups was not significant; this could be remedied in future studies by creating more triplicates of the experiment. However, it is important to note that bacteria did grow in all nine of the test tubes that the experiment was done in. Other future studies could be related to the concentration of each bacteria, to degrade the plastic even more.
