Synopsis of recent research by authors named "Hua-Xia Sheng"
- Hua-Xia Sheng's research primarily focuses on the sources and mechanisms of nitrous oxide (NO) production in marine environments, highlighting the significant role of particle-associated denitrification in oxic coastal waters as a key contributor.
- Through various nitrogen isotope labeling experiments, Sheng elucidates the pathways of NO production by ammonia-oxidizing archaea, providing insights into the kinetics of these processes and their implications for global NO budgets.
- Additionally, Sheng investigates the regulatory mechanisms between ammonium assimilation and oxidation in the marine nitrogen cycle, revealing how ambient nitrate concentration influences these pathways in the stratified ocean.
