^aLTAs were extracted with hot aqueous phenol and purified by HIC from different L. delbrueckii subsp. lactis strains. Unless stated otherwise, the values are based on NMR analyses. ND, not detected.

^bPolyols and α-glucose were quantified by GLC, and amino acids were quantified by the use of an amino acid analyzer.
