| Resumo: |
Studies were carried out on the isolation of diuron-degrading bacteria from treated soil. The mineralization of 14C-diuron in soil following a three-year application and in soil without previous application were 68.95 mug.100 g-1 and 24.16 mug.100 g-1, respectively, after a 64-day incubation period. In the first soil there was a significant increase in the number of bacteria, from 3.3 x 10 6 to 1.9 x 10(8). The microbial biomass did not change, however, a significant 14C-residue of diuron was found in the microbial biomass. A consortium of three bacteria, Acinetobacter johnsonii and two Bacillus spp., was isolated in medium containing diuron as the only carbon source. Only A. johnsonii was able to grow alone in medium with diuron as the only carbon source.
