Key Points

This research examines how cryptic sulfide-driven autotrophic denitrification contributes to nitrous oxide (N2O) production in a river-reservoir system.
Analyzed microbial community interactions in a seasonally hypoxic river-reservoir system.
Quantified N2O production linked to sulfide-driven denitrification activities.
Identified significant contributions of sulfide-driven denitrification to total N2O emissions.
Observed interactions between microbial community members that enhance denitrification processes.
Measured increases in N2O production during periods of reduced oxygen availability.

Implication

Measures the impact of cryptic sulfide-driven denitrification on N2O production, suggesting important ecological interactions.

Abstract

O production and provides novel insights into microbial community interactions in oligotrophic aquatic systems.
