AIDED PHYTOREMEDIATION TO CLEAN UP DIOXINS/FURANS-AGED CONTAMINATED SOIL: CORRELATION BETWEEN MICROBIAL COMMUNITIES AND POLLUTANT DISSIPATION
Meglouli, H., J. Fontaine, A. Verdin, M. Magnin-Robert, B. Tisserant, M. Hijri, et al.
Microorganisms 7(11): 523(2019)

Microcosm experiments that combined alfalfa with arbuscular mycorrhizal fungal inoculum (Funneliformis mosseae), biosurfactant (rhamnolipids), dioxins/furans degrading-bacterium (Sphingomonas wittichii RW1) and native microbiota amendments were conducted to phytoremediate aged dioxins/furans-contaminated soil. The total dioxins/furans dissipation was estimated to 23% after six months of culture in the combined test when compared to the non-vegetated soil. Dioxin/furan dissipation resulted from soil microbial enzyme activity simulation and an increase of bacterial abundance, richness, and diversity, as well as fungal diversity. Concomitant cytotoxicity and dioxins/furans concentration decreases were observed in the phytoremediated soil. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6920798/
