Gut remediation: Back to the future.

Probiotics alleviate the toxicity of environmental pollutants by regulating the composition and function of gut microbiota, which are termed as “gut remediation.” Compared to current remediation technology, gut remediation appears to be a novel remediation approach to repair tissue damage caused by various pollutants. Recently, gut remediation has been used for in vivo remediation of pollution. This chapter mainly reviews how to reduce heavy metals and organic contaminants in the gut. Some successful research cases are listed. Additionally, an essential consideration for probiotics is how to successfully introduce a/some strain(s) with desired function as well as robust colonization into recipient communities, which merit formulating probiotics regimen design based on the consumer in differing clinical contexts
