2.4. Production of exopolysaccharide
The screening for exopolysaccharide (EPS)-producing LAB
strains followed the method described by Garai-Ibabe et al. (2010),
slightly modified. The LABs were grown in MRS broth (pH 5.5) at
30 C in an atmosphere containing 5% CO2 for 48 h. The EPSp producing ability was evaluated by visual observation of the culture
viscosity.
