Dataset: Fecal PCB metabolites in germ-free mice compared to conventional mice

The PCB metabolome in feces of germ-free (GF) and conventional (CV) mice was systematically explored with nontarget high-resolution mass spectrometry (Nt-HRMS). The total PCB metabolite levels were dose and gut microbiome dependent. This finding demonstrate that the gut microbiome plays a role in the metabolism and excretion of PCB metabolites. This dataset summarizes relative levels of individual PCB metabolites in feces of both CV and GF mice, including the raw data files collected from instrument and raw data extracted for the mass chromatograms (i.e., area integration, putative molecular formulas, and analysis of isotope patterns).
