Exopolysaccharide production by Streptococcus thermophilus SY: production and preliminary characterization of the polymer

Aims: To evaluate the effect of yeast extract (YE) concentration, temperature and pH on growth and exopolysaccharide (EPS) production in a whey‐based medium by Streptococcus thermophilus SY and to characterize the partially purified EPS.
