Research on the enhancement mechanism of nitrite on heterotrophic nitrification and aerobic denitrification of Acinetobacter johnsonii EN-J1

Heterotrophic nitrification-aerobic denitrification bacterium Acinetobacter johnsonii EN-J1 was isolated and purified from vegetable cultivation soil, and the enhancement mechanism of nitrite on heterotrophic nitrification and aerobic denitrification was investigated, with the aim of providing provide a theoretical basis for the improvement and innovation of nitrogen removal technology.
