Biofilm formation. (A) Biofilm formed by B. firmus GB1and B. indicus HU36 on a solid MSgg medium. Plates were incubated 4 days at 37°C. Biofilm was visible after about 3 days. (B) Production of biofilm by B. firmus GB1 (black bars) and B. indicus HU36 (grey bars) in liquid MSgg medium supplemented with 0.5% fructose or 0.5% sucrose or 0.5% fructose and 0.5% sucrose. Data shown are representative of three independent experiments.
