This research shows that a beneficial bacteria called Lacticaseibacillus rhamnosus can help treat skin problems caused by chromate exposure, a common hazard for construction workers and factory employees. The bacteria work by reducing toxic chromate to a less harmful form through a special protein called flavin reductase. When tested on mice with chromate-induced skin damage, the probiotic treatment significantly improved skin healing and reduced inflammation. This suggests these beneficial bacteria could offer a safe, natural treatment for occupational skin conditions caused by heavy metal exposure.
