Fig 2.
Static biofilms of V. salmonicida LFI1238 and the ΔlitR strain formed in L15 medium at 4°C. The biofilms were visualized by phase-contrast microscopy after 3 days (A and B) and macroscopically after 6 days (C and D). No biofilm was formed by LFI1238 (A and C), whereas the ΔlitR strain (B and D) formed a thick and viscous biofilm under the chosen conditions.
