Table 1. Tentative Identifications and Dynamic Changes of Metabolites of TSA, EGCG and PCB2 during Fermentation with HFS.

^aSupporting mass spectrometric data can be found in Table S2, Supporting Information.

^bThese identifications were confirmed with authentic standards.

^cMean value of compound concentrations (n = 3) and n.d., not detected. The colors range from light blue to dark blue indicating the range from low to high relative concentration for each metabolite detected in all samples.

^dThe quantification of this compound was calculated based on 5-(4′-hydroxyphenyl)valeric acid, which may have different response factors, and thus resulted in overestimation in the concentration.
