Abstract:Hexavalent chromium reduction kinetic parameters were estimated for several mixed cultures using molasses as the carbon source and nitrate as the terminal electron acceptor. Mixed cultures were enriched from diverse environmental sources, and kinetic parameter comparisons are made between the consortia and a pure culture grown under the same conditions. A statistical analysis of the results indicated that some kinetic parameters exhibited significant differences, whereas others did not. It should be noted that those parameters with statistically significant differences were nonetheless numerically similar. Conservative values, therefore, could be assumed, or site-specific data obtained, for those parameters to design in situ bioremediation of chromium-contaminated sites.
