Five different types of bacteria were isolated from Municipal Solid Waste and identified asNeisseria subflava, Staphylococcus aureus, Corynebacterium kutscheri, Bacillus pasteurii and Aeromonasspecies. Of these five different types, Neisseria subflava and Staphylococcus aureus were capable ofgrowing on propoxur containing media. These two bacteria were grown on synthetic broth containing 100and 200 ppm of propoxur respectively for 12 days. Residual phenol produced as a metabolite was estimatedevery 24 hours by colorimetry using 4 – aminoantipyrine method. Degradation pattern showed that,Neisseria subflava and Staphylococcus aureus degraded propoxur into residual phenol and basiccompounds. Neisseria subflava showed constant increase in degradation of propoxur over the time after144hrs of exposure to propoxur at 100 and 200 ppm. Nevertheless, degradation of 200 ppm propoxur wascomparatively less than that of 100 ppm propoxur by Neisseria subflava. Staphylococcus aureus showedzigzag pattern of degradation indicating that for every 24 or 48 hrs of degradation of propoxur, there wasdecrease in growth rate indicating that the metabolite of propoxur was inhibiting the growth and then therewas recovery once again leading to increased growth rate for another 24 hrs. |
