Résumé
Biological denitrification is an environmentally sound pathway for the elimination of nitrogen pollution in wastewater treatment. Extreme environmental conditions, such as the co-existence of toxic organic pollutants, can affect biological denitrification. However, the potential underlying mechanism remains largely unexplored. Herein, the effect of a model pollutant, hydroxyethane-(1,1-bisphosphonic acid) (HEDP), a widely applied and consumed bisphosphonate, on microbial denitrification was investigated by exploring the metabolic and transcriptional responses of an isolated denitrifier, Pannonibacter sp. strain DN. Results showed that nitrate removal efficiency decreased from 85% to 50% with an increase in HEDP concentration from 0 to 3.5 mM, leading to nitrite accumulation of 204 mg L
