Researchers engineered bacteria that lock arsenic inside their cells rather than displaying it on their surface, removing over 96% of arsenic from water in just 5 hours — far faster than previous biological methods and forming a simple 'plug-and-play' biofilm filter for real-world use.
1
Both engineered bacterial strains removed over 96% of arsenic (at 10 µg/L) within 5 hours, substantially faster than typical biological systems that require 20–24 hours.
2
At the higher concentration of 100 µg/L, the constitutive-expression strain (MT047) still achieved 76.2% removal of As(III) and 55.9% of As(V).
3
Intracellular accumulation outperformed surface-display strategies in biofilm applications, with MT047 achieving 71.8% removal of 100 µg/L As(III) within 24 hours.
