Figure SM-2: Examples of EEM fluorescence spectra: (a) at pH 7.0 ± 0.1 of S-EPS from
GS-Eer, (b) with quenching effects obtained for 135 µmol/L of ACE, and (c) for 755
µmol/L of ERY. The white arrows indicate areas of interest, i.e. peaks A and B.

Figure SM-3: Modeling of the fluorescence data from Figure S2
(B-EPS from GS-Eer) using the Stern-Volmer model. The F0/F
curve is represented at the Ex/Em couple: 222 nm / 300 nm
(aromatic protein region) (in blue), and 277 nm / 305 nm (soluble
microbial by-product-like region) (in red).
