Image and yields of biofilms formed by B. cereus 0–9 and its ΔspoVG mutants. (A) Top view of the biofilms; (B) Side view of the biofilms in test tube; (C) The quantitative determination results of biofilm yields. Each bar represents the mean of all the measurements and its standard deviations; “*” means 0.01 < P < 0.05; “**” means P < 0.01. (1) B. cereus 0–9; (2) ΔspoVG; (3) ∆spoVG::spoVG168; (4) ∆spoVG::spoVG and blank MSgg medium was used for negative control (CK)
