Complete nitrification during Highly efficient aerobic heterotrophic nitrogen removal and metal ion tolerance by Pseudomonas citronellolis YN-21 exhibiting without the involvement of amo and hao genes

Pseudomonas citronellolis YN-21 exhibits remarkable heterotrophic nitrification-aerobic denitrification capabilities. This strain demonstrates a complex nitrogen cycling process, despite lacking crucial genes involved in nitrification. Additionally, YN-21 strain showcases strong tolerance towards acidity and high concentrations of metal ions.
