Phytoremediation
Cadmium quietly accumulates in urban garden soils, former orchard land, and lots near old industrial sites — and algae-based bioremediation could make those spaces safe to grow food in again without digging out and hauling away contaminated earth.
Scientists screened several types of microscopic green algae to find which was best at pulling a dangerous metal called cadmium out of contaminated water. One particular species turned out to be exceptionally good at it, soaking up nearly 95% of the cadmium present. The researchers also worked out how the algae accomplishes this feat, which could help people harness it to clean up polluted water and soil more reliably.
Key Findings
Coelastrella tenuitheca S93-3 achieved 94.87% cadmium removal efficiency at a concentration of 30 mg/L CdCl2
This strain outperformed all other microalgae species screened in the study
The study characterized the mechanistic pathways underlying cadmium uptake, providing a foundation for optimizing algae-based remediation
chevron_right Technical Summary
A green microalgae strain called Coelastrella tenuitheca S93-3 can remove nearly 95% of cadmium — a toxic heavy metal that persists in soil and water indefinitely — offering a biological, chemical-free approach to environmental cleanup. The study also mapped the biological mechanisms the algae uses, which could help optimize its use in real-world remediation.
