Analysis of the EPSs from BGCG11, NB1, MUT1, and MUT2 strains by size exclusion chromatography (SEC) coupled to multiangle laser light scattering (MALLS) detection. LS, light scattering detector set at 90°; RI, refraction index; UV-280, PDA detector set at 280 nm; Mw, weighted average molar mass; P, peak.
