Spectrophotometric method to screen TanA activity in L. plantarum. (a) Total metabolites (gallic acid + pyrogallol) released by a TanA+ strain (ATCC 14917) throughout a tannic acid-rich medium fermentation. In pink, the results obtained by the proposed colorimetric method; in gray, the ones obtained by UPLC-UV-QToF. (b) Pearson correlation between the colorimetric and the UPLC-UV-QToF method. (c) Total released metabolites by the six selected L. plantarum strains after 10 d of fermentation. In pink, the results of the colorimetric method; in gray, the ones of UPLC-UV-QToF.
