Fig. 3: Biofilm reduction activity of CHAPk and CHAPk-SH3bk on 24 h and 48 h preformed MRSA biofilm on the glass surface.

a The biomass attached to the glass surface post-treatment was measured as the optical density at 570 nm. b Graph representing the percentage of biofilm reduced using 0.05 μg/μl of CHAPk and CHAPk-SH3bk from the glass. c CLSM analyses of the DAPI (blue) and PI (red) stained MRSA 24 h biofilm on glass surface. The data is presented as means ± SD of three replicates, *P < 0.05, ns- non-significant, **P = 0.0020; ****P < 0.0001.
