3.2. Effect of dairy-based protein sources on EPS production
There were significant (Pb0.05) differences in the EPS levels between
the different dairy-based protein sources after 18 h fermentation,
in particular for B. longum subsp. infantis CCUG 52486. The
highest EPS levels among the four dairy proteins were with CH
(Fig. 1). In the case of B. longum subsp. infantis CCUG 52486, four
times higher EPS levels were obtained with CH than with LH. Moreover,
higher amounts of EPS were obtained with CH compared to the
control (YE) although the cell concentrations were not significantly
(Pb0.05) different between these two cases. In the case of B. infantis
NCIMB 702205 the highest EPS amount was produced by the control
