Cultivation of S. thermophilus LY03 in MST medium with pH control. Filled circles, lactose (mM); open circles, galactose (mM); filled triangles, lactate (mM); open triangles, optical density (OD620); filled squares, EPS (mg/1) quantified after precipitation by mass; open squares, EPS (μM repeating units) quantified from galactosamine peak after hydrolysis. The molar mass of the repeating unit is 762 g according to the NMR structure .
