Résumé
Cyromazine as insect growth inhibitor have been frequently detected in the environment, which show a potential threat to environment and soil health. Nitrogen is an essential component of all living organisms and the main nutrient limiting life on our planet. In this study, quantitative polymerase chain reaction (qPCR) and sequencing of nitrifying and denitrifying bacteria were conducted to investigate the dynamic effects of cyromazine on nitrogen conversion during laboratory-based composting. Results showed that the presence of cyromazine significantly reduced the abundance of amoA gene during the thermophilic phase of composting (p < 0.01), resulting in lower oxidation of NH
