“…A large number of technologies have been developed in order to clean up such sites. However, in some cases, biomonitoring has emerged as one of the most effective remediation strategies, especially where contaminant plumes can be retained within property boundaries in the subsurface and groundwater [ 3 ]. This has created a need for a variety of monitoring technologies, ranging from simple and rapid on-site assessments to elaborate laboratory measurements of contaminants [ 4 ].…”

This paper investigated the effects of binary mixtures of bioluminescence inducers (toluene, xylene isomers, m-toluate) and of metals (Cu, Cd, As(III), As(V), and Cr) on bioluminescence activity of recombinant (Pm-lux) strain KG1206. Different responses and sensitivities were observed depending on the types and concentrations of mixtures of inducers or metals. In the case of inducer mixtures, antagonistic and synergistic modes of action were observed, whereas metal mixtures showed all three modes of action. Antagonistic mode of action was most common for mixtures of indirect inducers, which showed bioluminescence ranging from 29% to 62% of theoretically expected effects (P(E)). On the other hand, synergistic mode of action was observed for mixtures of direct and indirect inducers, which showed bioluminescence between 141% and 243% of P(E).In the case of binary metal mixtures, bioluminescence activities were ranged from 62% to 75% and 113% to 164% of P(E) for antagonistic and synergistic modes of action, respectively (p-values 0.0001–0.038). Therefore, mixture effects could not be generalized since they were dependent on both the types and concentrations of chemicals, suggesting that biomonitoring may constitute a better strategy by investigating types and concentrations of mixture pollutants at contaminated sites.

“…The reduction of a range of pollutant compounds in various soil systems using either proprietary nutrients alone or proprietary nutrients with specific microbial inocula relative to a control is shown in Figure 1 (Ellis and Bewley, 1990). Substantial reductions were obtained by the addition of specific nutrients, but in most cases both the rate and extent of degradation were enhanced by bioaugmentation.…”

“…Several studies have shown a moderate level of success with the use of prepared bed/on-site remediation strategies on PAH contaminated soil (21,22,46,103,128,141,142). Overall, prepared bed/on-site remediation was found to degrade LMW PAHs relatively efficiently compared to in situ remediation.…”

AbstractPAHs and nitroaromatic compounds are toxic, mutagenic and carcinogenic environmental pollutants that are prevalent in petroleum contaminated soil and pose a serious threat to environmental and human health. Bioremediation is an economic and efficient means to remediate contaminated soil. This study examined the mutagenicity of soil from an aged gasworks site as it underwent bioslurry treatment. Soil extracts were separated into two fractions, one containing PAHs (non-polar neutrals) and the other, Nheterocyclic and oxy-PAHs (polar aromatic) compounds. Each fraction was tested with and without metabolic activation. Overall, the mutagenicity of both fractions in the presence of metabolic activation demonstrated a net increase. Only the direct mutagenicity of the polar aromatic fraction exhibited a net decrease. The expected mutagenicity, the summed mutagenicity of the individual chemicals in each fraction, greatly underestimated the direct mutagenicity of both fractions. Only in the presence of metabolic activation did the predicted values exceed the observed. It is possible that the unexpected mutagenicity is the result of bacterial degradative by-products suggesting that mutagenicity monitoring of contaminated sites is required during bioremediation.Reproduced with permission of the copyright owner.

Development of a microbiological treatment for restoration of oil contaminated soil

Abstract: This paper describes the laboratory development of a microbial treatment for soil contaminated with oil hydrocarbon residues at a disused refinery site and the application of this technology in a pilot scale treatment bed in the field.
