From: Bacterial chemotaxis towards polysaccharide pectin by pectin-binding protein
Chemotaxis assay of strains Δsph1118 and Δsph1119. Chemotaxis of strain Δsph1118 cells towards alginate (A) but not towards pectin (B). Chemotaxis of sph1118-complemented strain Δsph1118 cells towards pectin (C). Chemotaxis of strain Δsph1119 cells towards alginate (D) and pectin (E). Except for the plate (B), the grey area in the middle of the plate stems from accumulating cells. Each plate assay was replicated three times independently. The profile of each plate is not an image cropped from different parts of the same plate or from different plates.
