Abstract
A no. of bacterial spp. was isolated from vegetable oil contaminated industrial wastewater. Out of 25 isolates, one isolate was selected for further studies on the basis of high degradation ability of Tw20. The isolated bacterial sp. was identified according to morphological and biochemical tests. The optimum degradation ability of isolated bacteria for Tween 20 (Tw20) was investigated under different pH levels (6.0, 6.5, 7.0, 7.5, 8.0, 8.5, and 9.0), different temperatures (250C, 300C, 350C and 400C) and different concentrations of Tw20 (1, 1.5, 2, 2.5 and 3%). Maximum degradation of Tw20 was recorded at the concentration of 1.5% of Tw20 at pH 8 and 300C temperature. Bacterial isolate was tested in LM media, supplemented with 1% coconut oil, at 300C for 13 days at 150rpm. Isolated bacterial sp. was able to degrade coconut oil and utilized FFA (Free fatty acids) as a carbon source. In oil contaminated wastewater, isolated bacteria f...
