Fig. 3From: Display of a β-mannanase and a chitosanase on the cell surface of Lactobacillus plantarum towards the development of whole-cell biocatalystsSurface localization of ManB and CsnA in L. plantarum cells. The panels show representative flow cytometric (a) and microscopic (b) analyses of L. plantarum cells harboring plasmids designed for cell-surface display of ManB and CsnA. The L. plantarum strains harboring ManB- or CsnA-encoding plasmids are denoted by different colors in the flow cytometry histograms (a) and different numbers in the micrographs (b): pSIP_1261ManB (blue, 1), pSIP_1261CsnA (red, 2), pSIP_ManBcwa2 (green, 3), pSIP_CsnAcwa2 (purple, 4). L. plantarum harboring an empty vector was used as negative control pEV (black, 5)Back to article page
