Figure 3. Biofilm formation during growth with shaking in liquid medium.
Following growth with shaking in LBS medium supplemented with 10 mM CaCl2, wild-type strain ES114 (left) presents a very faint ring and no clump, while the ΔbinK mutant (right) exhibits clumps (white arrow) and rings (black arrow) connected by “trees”. These cultures were imaged after 24 hours of shaking at 24°C.
