Growth of bacterial biofilms in the MBEC assay. (A) Mean cell density of Pseudomonas aeruginosa ATCC 27853 biofilms on the pegs in different rows of the MBEC assay. Each value is expressed as the mean and standard deviation of 4 to 6 trials. There is no significant difference between cell density of biofilms in the different rows (p = 0.842 using one-way ANOVA). (B) SEM photomicrograph of a P. aeruginosa biofilm on the peg surface. (C) Mean cell density of Escherichia coli TG1 on the pegs in different rows of the MBEC assay. Each value is expressed as the mean and standard deviation of 4 to 6 trials. There is no significant difference between cell density of biofilms in the different rows (p = 0.274 using one-way ANOVA). (D) SEM photomicrograph of an E. coli biofilm on the peg surface. The bar represents 5 μm.
