Table 4.

Thickness of biofilm observed by CLSM. The experimental data are expressed as the mean ± standard deviation (n = 3), and differences in thickness among live cells are expressed with different lowercase superscript letters (p < 0.05). Differences in thickness among dead cells are expressed with different capitalized superscript letters (p < 0.05).
