Differential expression of biofilm promoting factors. (A) Effect of minimal media (MM) and rich media (CFA) with or without salt on biofilm formation. (B) Simplified model of the regulatory network regulating curli and cellulose in S. enterica. (C–F) Effect of different media and cya mutation on the expression of biofilm effectors and regulators csgD, csgB, adrA, and mlrA, in cultures grown in the indicated media for 72 h at 25°C on a 24-well polystyrene plate. ^∗p < 0.005, ^∗∗p < 0.005, ns: non-significant.
