Commensal Bacteria in the Gut Microbiome Encode Previously Unrecognized Aromatic Hydrocarbon Catabolic Machinery
Introduction. Polycyclic aromatic hydrocarbon (PAH) toxicology has been primarily defined by host metabolic bioactivation to reactive intermediates. Yet ingested PAHs and biliary-delivered metabolites also enter the intestinal lumen, where they encounter the gut microbiota, an additional but understudied metabolic comp...
