Zhang Y, Wang X, Dong X, Cai J, Gao W
Summary
4.5/10A newly discovered bacterium (Paracoccus sp. QD-21) can simultaneously perform nitrification and denitrification, making it potentially useful for removing nitrogen from wastewater more efficiently than conventional treatment methods.
Key Findings
Paracoccus sp. QD-21 exhibits dual metabolic capability: heterotrophic nitrification and aerobic denitrification simultaneously
Nitrogen removal rates achieved: 5.55, 3.35, and 2.78 mg/(L·h) for different nitrogen substrates
Novel strain isolated for practical application in wastewater nitrogen removal treatment systems
Original Abstract
A novel strain of Paracoccus sp. QD-21, which is capable of simultaneous heterotrophic nitrification and aerobic denitrification, was isolated and investigated for the potential in removal of nitrogen in wastewater treatment. The strain exhibited nitrogen removal rates of 5.55, 3.35, and 2.78 mg/(L·h) for NH
