Abstract

Bioremediation of phenol was done using Candida tropicalis SSK01 immobilized cells isolated from petroleum contaminated soil. Optimization of phenol degradation studies was carried at 30?C to 40?C, pH 6 to 8 and initial concentration of 300 mgl-1 to 900 mgl-1. Candida tropicalis SSK01cells immobilized using sodium alginate were used in phenol degradation studies. Optimization of phenol degradation was performed by Central Composite Design (CCD). A total of 20 experiments were carried out and the optimal degradation of 95.2% was observed at 34.20 ˚C at pH 6.86 with initial concentration of 610 mgl-1.The R2, adjusted R2 and Predicted R2 values were 0.9976, 0.9955 and 0.9919 respectively which indicates that experimental values are in good agreement with the predicted values. ?
