Left and middle. Pre-expanded and expanded biofilms as visualized by CLSM. Pre-expanded and expanded biofilms were labelled with SYTO 13 and Alexa Fluor 555 NHS ester, respectively. Scale bars: 10 μm. Inset scale bars: 2 μm. Expansion factors are 2.5, 3.6, 2.6 and 2.8 for L. reuteri, E. faecalis, S. marcescens and S. aureus, respectively. Right. Non-expanded biofilms as visualized by SEM. Magnifications are ×1000 (×9000, inset) for L. reuteri and E. faecalis; ×3000 (×5000, inset) for S. marcescens and ×3000 (×9000, inset) for S. aureus.
