Extreme-environment microbes offer a new toolkit for cleaning up pollution

Phytoremediation
Soils contaminated with heavy metals or petroleum can sit toxic for decades because ordinary microbes can't do the job; the hardy organisms reviewed here already break down those same compounds in naturally extreme environments, pointing toward cleanup methods that could restore damaged land near you.
Some microbes live in places most life can't survive: volcanic hot springs, highly acidic mine runoff, or intensely salty lakes. To stay alive there, they've evolved special enzymes that can chew through toxic substances like heavy metals, plastic residues, and petroleum compounds. Scientists are now cataloguing how these abilities work at the molecular level so they can put these microbes to work cleaning up polluted soil and water.
Key Findings
Extremophiles possess specialized enzymes (extremozymes) active under conditions that inactivate conventional microbial enzymes, making them viable for remediation in harsh contaminated sites.
The review identifies molecular mechanisms by which extremophiles degrade three major pollutant classes: plastics, toxic metals, and petroleum-derived compounds.
Current limitations center on scaling lab-demonstrated capabilities to field applications, with the review outlining priority research directions for practical environmental biotechnology.
chevron_right Technical Summary
Microorganisms that thrive in extreme environments (think boiling springs, highly acidic rivers, or salt flats) carry enzymes capable of breaking down plastics, heavy metals, and petroleum spills where ordinary microbes fail. This review maps their biological strategies and charts a path toward using them in real-world pollution cleanup.

Soil health is the capacity of soil to function as a living ecosystem, supporting complex interactions between microorganisms, soil fauna, and plant communities. For plant science, soil health is critical because these biological and chemical soil properties directly control nutrient availability,
