Extremotolerant Microbes Explore Nutrient Recycling for Space Life Support – GeneOnline News
Extremotolerant Microbes Explored for Nutrient Recovery in Space Life Support Systems
A new meta-analysis investigates how extremotolerant microbes could help address nutrient gaps in bioregenerative life support systems during long-duration space missions. Published on December 13, 2025, the study examines how these hardy organisms might support human survival by recycling nutrients and backing food production within closed-loop ecosystems essential for extended space travel.
The review emphasizes that extremotolerant microbes can endure and prosper under severe conditions—think extreme heat or cold, high radiation, and scarce resources—paralleling the challenges faced in space. Researchers aggregated data on microbes capable of nitrogen fixation, carbon cycling, and other fundamental biochemical processes that sustain balanced ecological systems. Their conclusions indicate that integrating these microbes into bioregenerative life support could alleviate nutrient depletion over time, potentially boosting system sustainability and decreasing the need for frequent Earth resupply missions.
