Cellulose production is critical for wrinkled morphology. a Mutant Δ08765 showed a wrinkled morphology, whereas the wild-type and Δ08765ΔbcsZB strains showed a smooth morphology in SW-LB medium. b Floating biofilm formed by the Δ08765 and Δ08765ΔbcsZB mutant strains in SW-LB and 2216E medium. At least two independent experiments were performed with each strain, and only representative images are shown in a and b
