Fig. 4: Pigment identification in Latilactobacillus fragifolii AMBP162 and Lactiplantibacillus plantarum WCFS1.

Lt. graminis DSM20719T was used as a nonpigmented control. A Washed cell pellets (left) and unpurified extracts (right) of 2-day cultures. B UV chromatogram of the HPLC eluent of the extracted pigments. C UV‒visible absorption spectrum of the highest peak in the HPLC chromatogram; absorption maxima (nm) are indicated above the peaks. D High-resolution quadrupole time-of-flight mass spectrometry image of the highest peak in the HPLC eluent. The mass-to-charge ratios are indicated above the peaks.
