Description
Balázs György and co-authors test whether kefir grains can pull toxic metals out of water, in a 2024 study. Kefir grains are the rubbery starter clumps used to ferment drinks, made of natural polymers. Standard metal removal is costly and uses harsh chemicals, so a cheap living material is attractive. The team compared grains from water kefir and milk kefir against copper and arsenic in solution.
Milk kefir grains performed better, above all for copper, removing up to ninety-five percent at low levels. Their peak uptake was measured and compared with the water grains' weaker showing. Arsenic removal was also tested for both types. The study supports farm and dairy waste streams as sources of low-cost cleaning material for polluted water.
