Novel Alkalitolerant Marine Strain M4: Denitrification and Phosphate Removal Performance and Molecular Mechanism Study.

The aim is to screen strains in seawater that exhibit high alkalinity tolerance in marine environments and possess efficient denitrification and phosphorus removal capabilities, thereby developing their application potential in marine ranching, saline-alkali land, and aquaculture effluent treatment. By measuring the activity of key nitrogen and phosphorus metabolic enzymes and conducting whole-genome sequencing analysis of the strains, this study aims to elucidate their specific denitrification and phosphorus removal mechanisms and metabolic pathways. This research provides a theoretical foundation and innovative research methods for studying the metabolism of similar bacterial strains.
