Nanoplastics enter through food and water and can reach the brain and kidneys. A bacterium from kimchi may be the body’s new defense.
Researchers at South Korea’s World Institute of Kimchi identified that Leuconostoc mesenteroides CBA3656 a lactic acid bacterium found in kimchi binds to polystyrene nanoplastics in the gut through a process called biosorption. Under simulated human intestinal conditions it maintained 57 percent adsorption efficiency while a comparison strain dropped to just 3 percent. In germ-free mouse experiments mice given the probiotic excreted more than twice the amount of nanoplastics in their f***s compared to untreated mice. The study was published in Bioresource Technology in February 2026. Human trials are still needed before clinical conclusions can be drawn.
