%X The effect of exposed to mefenacet in short term on the activities of superoxide dismutase (SOD), catalase (CAT) and ATPase of Sphingobacterium multivorum Y1 capable of degrading mefenacet was studied. The results showed that mefenacet induced obviously SOD activity in S. multivorum Y1, especially to those in exponential phase, and also greatly stimulated CAT activity. The stimulation process of CAT activity was similar to that of SOD activity at different growth phases in S. multivorum Y1 by mefenacet. The level of ATPase activity increased after application of mefenacet, but there existed no good correlation with the growth phase of bacteria. It was feasible definitely to use antioxidant enzyme combined with ATPase as a biomarker for pollution stress of these chemicals in soil environment.
