The chemical cycles carried out by bacteria and archaea living in coastal sediments are vital aspects of benthic ecology. These ecosystems are subject to physical disruption, which may allow for increased respiration and complex carbon consumption - impacting chemical cycling in this environment often thought to be a terminal place of deposition. We use the redox-enzyme sensitive probe RedoxSensor Green to measure rates of electron transfer physiology in individual sulfate reducer cells residing in anoxic sediment, subjected to transient exposure of oxygen and laminarin.

- The study highlights the challenges in measuring microbial process rates and linking them to specific microorganisms in low-biomass environments, focusing on sulfate reduction and methanogenesis.
- Researchers utilized the RedoxSensor™ Green probe to assess microbial activity in the low-cell-density groundwater of Death Valley, revealing active sulfate-reducing bacteria, especially Desulforudis audaxviator, using acetate and hydrogen as electron donors.
- The findings demonstrate the effectiveness of this method for understanding single-cell anaerobic metabolism and establishing connections between genetic information and microbial functions in challenging environments.
