The collected soil was from Froberg Farm, where several vegetables along with strawberries are grown. The soil was dark brown in color and heavily moistened. During the process of isolating and growing the bacteria present in the soil sample, I have observed color changing patterns in a weekly basis on specific combination of medium and insecticide. The results are as follows: Week 1, 9/21/2011 Paraoxon (Px)+ CSM = pronounce yellow color (Y) Paraoxon (Px)+ SSM = yellow color and lightly turbid, (C) Methyl Parathion (MP) + CSM = pronounce yellow color (Y) Methyl Parathion (MP) + SSM = yellow color and lightly turbid, (C) Week 2, 9/28/2011 Paraoxon (Px)+ CSM = pronounce yellow color (Y) Paraoxon (Px)+ SSM = Colorless (T) Methyl Parathion (MP) + CSM = yellow color and lightly turbid (C) Methyl Parathion (MP) + SSM = Colorless (T) Week 3, 10/05/2011 Paraoxon (Px)+ CSM = pronounce yellow color (Y) Paraoxon (Px)+ SSM = Colorless (T) Methyl Parathion (MP) + CSM = yellow color and lightly turbid (C) Methyl Parathion (MP) + SSM = Colorless (T) Week 4, 10/12/2011 Paraoxon (Px)+ CSM = pronounce yellow color (Y) Paraoxon (Px)+ SSM = Colorless (T) Methyl Parathion (MP) + CSM = yellow color and lightly turbid (C) Methyl Parathion (MP) + SSM = Colorless (T) Week 5, 10/19/2011 Paraoxon (Px)+ CSM = pronounce yellow color (Y) Paraoxon (Px)+ SSM = Colorless (T) Methyl Parathion (MP) + CSM = yellow color and lightly turbid (C) Methyl Parathion (MP) + SSM = Colorless (T) Around 80-90 colonies of bacteria were successfully isolated from the soil sample and grown well on the CSM Agar media with Paraoxon pesticide
