Qualitative analysis of benzaldehyde toxicity: CLSM images of 24-h planktonic cultures and 3-day-old Z. mobilis biofilms stained with the BacLight LIVE/DEAD viability stain. Planktonic (A) and biofilm (B and C) cultures were examined after 1 h of exposure in the absence or presence of benzaldehyde. Live cells fluoresced green, and dead cells fluoresced red. The top and bottom images in panel B are topical and vertical views of Z. mobilis microcolonies. (C) Overall biofilm morphology. (A and B) Bars, 50 μm. (C) Bars, 200 μm.
