Fig. 6

Bright-field microscopy images showing calcium and chelator effects on biofilm formation at 48 h of L. plantarum ATCC 14917. CDM medium was supplemented with 0, 10, or 25 mM CaCl2 (a–c) and 0 mM CaCl2 + 50 mM EGTA, 10 mM CaCl2 + 80 mM EGTA, or 25 mM Cl2 + 100 mM EGTA (d–f). The scale bar (2 μm) shown on image (a) applies to all images (a–f). Corresponding zoomed out images are shown in Supplementary Fig. S10.
