Figure 8. Biofilm formation by F. novicida U112 and Δhfq strains.
Both strains were assayed for biofilm formation using crystal violet staining after 48 hours of static growth in MH broth at 37°C. Culture OD590 nm was determined for multiple replicates. U112 demonstrated decreased crystal violet straining compared to Δhfq (p<0.0001).
