Figure 3: Degradation of paraoxon to p-nitrophenol by bacterial soil isolates. Starting concentration of paraoxon is 100 ug/mL. Absorbance readings were taken at 405 nm to detect the concentration of p-nitrophenol in the media over a period of 72 hours. P. aeruginosa strain ATCC 10145 was used as a negative control.Error bars represent 95% confidence intervals.
