Initial-phase optimization for bioremediation of munition compound-contaminated soils

Article Abstract:

The optimum conditions for bioremediation of munition compound-contaminated soils were established. The procedure called for the establishment of anaerobic conditions by phosphate buffer flooding of contaminated soils followed by the addition of potato starch. Optimum pH was set at low to neutral at a temperature range of 20 to 37 degrees celsius. Addition of a nitrogen source also contributed to the remediation of soils. Application of all these conditions resulted in a highly increased rate of the reductive phase of 2,4, 6-trinitrotoluene degradation.

Degradation of 2-sec-butyl-4,6-dinitrophenol (dinoseb) by Clostridium bifermentans KMR-1

Article Abstract:

High-performance liquid chromatography is used to degrade 2-sec-butyl-4,6-dinitrophenol (dinoseb) with a strain of Clostridium bifermentans acting as a biocatalyst. The degradation process is performed below the limit of detection with no accumulation of aromatic intermediates. Results show that C. bifermentans can easily mineralize the anaerobic degradation products of dinoseb.
