Mutation of slpB gene drastically affects surface proprieties in P. freudenreichii CIRM-BIA 129. (A) The surface net charge was determined by measuring the ζ-potential. (B) The surface hydrophobicity was determined by quantifying adhesion to solvents (Xylol, Chloroform, and Ethyl Acetate). Wild-type (WT) and mutant CB129ΔslpB strains were compared. Bar represents the mean SD of three biological replicates and three technical replicates. The asterisks (****) denotes the statistical significance of the represented value between CB 129 WT and CB 129ΔslpB (p > 0.0001).
