Degradation of Dinitrotoluenes by Bacterial Suspension Cultures

Popis výsledku v původním jazyce

This study was focused on the selection of pure bacterial strains being able to degrade dinitrotoluenes (DNT). The effects of environmental parameters i.e., initial pollutant concentration, pH, and the presence of cosubstrates on the rate and efficiencyof 2,4-DNT and 2,6-DNT biodegradation were examined. The pure bacterial cultures were isolated from a mixed culture that originated from a long-term contaminated soil near the Explosia plant (Pardubice, Czech Rep.). The degradation experiments were performed in batch aerobic submerged cultivations. The optimal degradation properties were found with Pseudomonas putida at pH 7. These results were compared with those obtained with the mixed culture. It was concluded that the enrichment mixed bacterial culture appeared to be an effective biocatalyst for a remediation of contaminated sites by 2,4-DNT.
