Mesocosm sludge bioreactors under sustained 3-chloroaniline (3-CA) stress (with controls) Metagenome and Metatranscriptome

This study demonstrated the impact of a sustained stress on activated sludge community and wastewater treatment process and its subsequent recovery. Using a combination of techniques in a controlled and replicated experiment, it was shown that microbial communities can evolve degradative capacity following a sustained xenobiotic input, specific functions like nitrification can fully or partially recover and targeted culture-independent approaches can be used to elucidate the mechanisms of adaptation.
