The invention provides a novel strain of cadmium-removing Lactobacillus plantarum bacterium, CCFM8610, which has a good tolerance to acidic environments. Lactobacillus plantarum CCFM8610 has a good tolerance to cadmium-containing medium and can effectively bind cadmium in vitro. Animal studies have shown that it can effectively reduce tissue cadmium accumulation and facilitate fecal cadmium excretion. Lactobacillus plantarum CCFM8610 has a great potential to be used as an active ingredient in cadmium-removing pharmaceutical drugs and fermented foods.
