Summary

Story summary

A study by Lisa Keller at Montana State University shows a Yellowstone bacterium can use both oxygen and sulfur for energy, challenging existing microbial respiration theories.
This dual energy strategy improves energy production in variable oxygen environments.
The findings may indicate similar mechanisms in other microbes, providing insights into early Earth's adaptation.
Implications include enhanced bioreactor efficiency and environmental cleanup, highlighting the importance of realistic experimental designs.
The research is published in Nature Communications.
