This microbial consortium degraded 2, ngTEQ/kg of 2,3,7,8-TCDD congener in soil, equivalent to lost of total toxicity in comparison to the control without bacterial seeding (4, ng TEQ/kg). Such a high ratio of dioxin degradation by a bacterial consortium was reported here for the first time, contributing more evidences for convincing the successful dioxin bioremediation of “Active Landfill” technology at large scale in Z1 area at Bienhoa airbase, Dongnai, Vietnam. | Degradation of 2 3 7 8-TCDD by a consortium of bacterial strains isolated from heavil herbicide dioxin contaminated soil in Bienhoa airbase
