This study presented effects of SMX on aerobic denitrification by an aerobic denitrifier strain Pseudomonas stutzeri PCN-1. Results demonstrated serious inhibition of N2O reduction as SMX reached 4 mu g/L, leading to higher N2O emission ratio (251-fold). Increase of SMX (similar to 8 mu g/L) would induce highest nitrite accumulation (95.3 mg/L) without reduction, and severe inhibition of nitrate reduction resulted in lower nitrate removal rate (0.15 mg/L/h) as SMX reached 20 mu g/L. Furthermore, corresponding inhibition of SMX on denitrifying genes expression (nosZ &amp;gt; nirS &amp;gt; cnorB &amp;gt; napA) was found with a time-lapse expression between nosZ and cnorB. Meanwhile, the decline in electron transport activity and active microbial biomass of strain PCN-1 was revealed. The insight into mechanism of SMX influence on aerobic denitrifier is of particular significance to upgrade nitrogen removal process in antibiotics-containing wastewater treatment plant.
