Summary

Pseudomonas cepacia and aNocardia sp., isolated from flooded alluvial soil amended with carbofuran, metabolized ring-14C-carbofuran fairly rapidly in mineral salts medium or soil extract, supplemented with yeast extract. When the two isolates were incubated with soil extract together with 500 μg ml−1 yeast extract, about 40 to 62% of the radioactivity was recovered as water-soluble products. The degradation of carbofuran byNocardia sp. led to the formation of coloured, water-soluble and non-extractable metabolites.
