Abstract:Comparison of amoA mRNA (ammonia mono-oxygenase encoding mRNA) was examined due to inhibition from Cd2+ (1, 5, 10mg/L) and Zn2+(5, 20, 50mg/L) during a short reaction period (6h). The real-time reverse transcription- PCR method was applied to detect profile of amoA mRNA in activated sludge quantificationally. Different performance of mRNA was observed during Cd2+ and Zn2+ inhibition test respectively, the highest inhibitory rate up to 53% at 10mg/L Cd2+ was discovered. The nitrifying inhibition was possibly performed through the impact on transcription of amoA mRNA by some heavy metals.
