The chromatogram shows that there was shift in λmax from 224 nm to 270 nm during 0 hours of incubation to 96 hours of incubation at 30°C on a rotary shaker in the dark. These results were obtained using at wavelength range 200 to 800 nm using Cary 300 UV-visible Spectrophotometer. This was an indication that isolate MD2 was able to degrade Aroclor 1260 into chlorobenzoates and derivatives which have wavelength ranging from 244 – 270 nm.
