Enhanced sulfide-driven autotrophic denitrification/ammonium oxidation process via metabolic cooperation of anaerobic bacterial consortia in a packed-bed bioreactor

Key Points

• Enhanced denitrification occurred with a notable reduction in nitrogen compounds, optimizing resource recovery.
• Performance metrics showed a 30% increase in ammonium oxidation efficiency under anaerobic conditions.
• Investigative methods included a packed-bed bioreactor analysis featuring various anaerobic bacterial consortia and their interactions.
• The findings suggest metabolic cooperation among bacteria could significantly advance wastewater treatment processes.
