(A) SDS-PAGE of surface proteins. Equal amount of volume (14 μL) of the extracted polypeptides were loaded to each well; from left to right: S-layer extracted from Lactobacillus reuteri; Molecular weight marker (kDa), S-layer extracted from Lactobacillus plantarum. (B) Two-dimensional gel electrophoresis of S-layer polypeptides extracted from L. plantarum and L. reuteri.
