nitrogen-metabolism
Nitrogen metabolism is the process by which plants uptake, assimilate, and utilize nitrogen from their environment to synthesize essential compounds such as proteins, nucleic acids, and chlorophyll. Nitrogen is often the most limiting nutrient for plant growth and productivity, making its efficient metabolism critical for plant development and biomass accumulation. Understanding nitrogen metabolism at the molecular and physiological level is fundamental to improving crop performance, optimizing nutrient use efficiency, and advancing sustainable agricultural practices.

A 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.
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
