Biological transformation of oxyfluorofen in soil
Abstract: Oxyfluorofen (2-chloro–4-trifluormethylbhenyl-3-ethoxy-4-nitrophenyl ether) is a diphenyl ether herbicide used for the control of broad leaved weed in many crops. Thus a knowledge of the precise biochemical mechanisms of this compound may lead to added confidence in the long term use of herbicide.
The co- metabolism of oxyfluorofen by soil leachate microorganisms indicated that this herbicide was easily metabolozed in the presence of nutrient broth, thus after one month more than 95% of the initial dose ( 100 ppm ) was utilized.
The whole cell incubation experiment showed the microorganisms
Grown on oxyfluorofen in the presence of nutrient broth were capable of metabolizing this herbicide as the sole substrate indicating that oxyfluorofen metabolizing enzymes were fully induced in these microorganisms.
The T . L. C. separation of the culture extracts of oxyfluorofen , indicates the presence of three major metabolites which were isolated in pure form . The infra – red spectrum of the major metabolite ( A ) was obtained and the investigation of the structure of this intermediate showed that metabolite ( A ) was very similar in structure to the original com- pound except in the replacment of the number 2 group present in the herbicide by an amino group which was present in metab . A indicating that the initial step in the co-metabolism of this herbicide is the reduction of oxyfluorofen to its amino derivative .
