Fig. 3From: Constitutive expression and cell-surface display of a bacterial β-mannanase in Lactobacillus plantarumSurface localization of ManB in L. plantarum cells analyzed by flow cytometry (a) and immunofluorescent microscopy (b). L. plantarum strains harboring ManB-encoding plasmids are depicted by different colors in the flow cytometry histograms (a) and different numbers in the micrographs (b): pPgm_1261Man (blue, 1, an arrow indicates the ‘shoulder’ of surface mannanase detected by slight shift in the fluorescent signal); pSlpA_1261Man, (green, 2); L. plantarum harboring an empty vector pEV was used as negative control (black, 3)Back to article page
