| Abstract: | A bacterial strain isolated from soil and identified as Pseudomonas alcaligenes, was able to hydrolyze four phenylcarbamate herbicides (CIPC, BIPC, IPC and swep) to corresponding anilines and alcohols by co-metabolism. The pH of the growth medium had little influence on bacterial growth and rate of herbicide transformation. Increase in CIPC and BIPC concentrations resulted in a significant inhibition of bacterial growth and herbicide degradation. Using a range of antibiotics it was shown that the enzyme involved in degradation was inducible. |
