Figure 1. S. mutans UA159 copZ mutant is defective in biofilm formation.

Figure 1

Single-gene mutants of copYAZ and the parent strain were allowed to form biofilms for 18 hours in biofilm media supplemented with 1% sucrose. Biomass was quantitated by crystal violet staining and reading at O.D.562. Complement strain of ΔcopZ restored biofilm formation (ΔcopZ/copZpVPT). **=p<0.01. Data represents three biological replicates.
