Researchers in Uzbekistan discovered three types of bacteria that can remove dangerous heavy metals like cadmium and nickel from contaminated soil. These bacteria work by clinging to the metal particles on their surfaces and even chemically transforming them into less harmful forms. The study found that these bacteria work best at neutral pH and warmer temperatures, making them promising candidates for cleaning up polluted environments naturally and affordably.
