To better understand EPS chemical structure, further 2D NMR experiments were performed and results are presented inside the manuscript. In short, they allow to clearly identify the D-mannose α-(1→2) and α-(1→4) linkages in EPS. These results suggest they are the prevailing units of the EPS backbone making it a branched one. Also, β-glucopyranose and β-galactopyranose structures were identified and the acetylation was confirmed.
