Effect of acclimation and nutrient supply on 5-tolyltriazole biodegradation with activated sludge communities.

Highlights: [•] 5-Tolyltriazole biodegradation significantly improved by biomass acclimation. [•] Biodegradation enhancement by non-specific sludge supernatant addition. [•] Nitrogen addition also increased biodegradation rate. [•] Degradation presumably starts by benzene ring cleavage serving as a carbon source. [•] Heterocyclic N-containing ring is assumed not to be cleaved necessitating N-supply. [ABSTRACT FROM AUTHOR]
