Adhesion Strength

vline gray 1

Once planktonic microbial cells form a biofilm, it gets more and more difficult to destroy those microbes. Biofilms can adhere to biotic and abiotic surfaces as a defense mechanism against antimicrobial compounds and other external dangers.

With the BioFlux, analyzing biofilm adhesion is simple. Controlled, shear flow is used to treat biofilms with antimicrobial compounds, biosurfactants, or other solutions that alter adhesion.

P. aeruginosa, S. aureus, and co-culture of both stains were grown on BioFlux plates for 48 hours (A, C, and E, respectively). They were then treated with rhamnolipids and sophorolipids, both known biosurfactants, which disrupted the biofilm formation and adhesion (B, D, F). Viable cells stained green and dead cells stained red (Banat et al., 2016).
