Figure 6

Biofilms of S. oneidensis MR-1 wild type, ∆ arcS , ∆ arcA , ∆ barA and ∆ uvrY mutants. CLSM images of S. oneidensis MR-1 wild type, ∆arcS, ∆arcA, ∆barA and ∆uvrY mutant biofilms grown in LM in a hydrodynamic flow chamber. CLSM images were taken at 24 h (left column) and 48 h (right column) post-inoculation. Scale bars are 30 μm.
