Electronic Thesis and Dissertation Repository
Toxic metals are a class of elements with no biological role but with extreme toxicity. On average only 50% of ingested toxins are absorbed into the human body, for reasons still unknown. It was hypothesized that the gut microbiota plays a role in reducing toxin absorbance. The aim of this study was to determine if constituents of the gut, namely Lactobacillus species, are able to sequester arsenic, lead and cadmium from the environment. Lactobacilli were incubated with the metals, both in vitro and with a Caco-2 cell line. Analysis of metal concentrations was conducted to determine if these were reduced …
