Scanning electron microscopy (SEM).

<p>SEM analysis was performed to investigate the photocatalysis-induced deformation of bacterial cells. SEM images of <i>B. cenocepacia</i> cells (strains P2: A–D and BC14: E–H) with (A, C, E, G) or without (B, D, F, H) photocatalysis were taken. Arrows in C and G indicate the cellular deformations. Inserts in E and F are the respective low magnification views of biofilm-like bacterial clusters. Scale bars: 5 µm in A, B, E, F; 2.5 µm in C, D, G, H; 10 µm in the insets of E and F.
