Figure 4

Scanning electron microscopy images of the effect of the PES on Candida albicans biofilm on a polystyrene surface for three samples: A2 isolate ((a), (b)), 31MC isolate ((c), (d)), and ATCC90028 reference strain ((e), (f)). Biofilms without the PES ((a), (c), and (e)) and biofilms with the PES (273.43 μg/mL of total phenol content in gallic acid) after 24 h ((b), (d), and (f)) at 350x magnification.
