Evaluating Inhibitor Effects on Pellicle Formation in Bacillus subtilis

Source: Bucher, T., et al. Methodologies for Studying B. subtilis Biofilms as a Model for Characterizing Small Molecule Biofilm Inhibitors. J. Vis. Exp. (2016)This video demonstrates a pellicle formation assay using Bacillus subtilis to evaluate small-molecule inhibitors that disrupt matrix synthesis and biofilm development, providing a model to screen compounds that selectively inhibit surface-associated growth without affecting free-floating cells.
