Fig. 2: Biofilm reduction activity of CHAPk and CHAPk-SH3bk on 24 h preformed MRSA biofilm on the steel surface.

a The biomass attached to the steel 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 steel surface. The data is presented as means ± SD of three replicates, *P < 0.05, ns- non-significant, **P = 0.0020; ****P < 0.0001.
