Chloramphenicol but polysorbate-80 or ursolic acid reduces S. marcescens biofilm biomass. ac S. marcescens biofilms were treated with a chloramphenicol: 0.08, 0.80 mg/ml, b ursolic acid at 0.03 mg/ml or c 1, 0.1 0.01% polysorbate-80 (PS80). d Representative pictures of in vitro S. marcescens biofilms treated with chloramphenicol, polysorbate-80 (PS80) and ursolic acid (UA) at shown concentrations. Absorbance (540 nm) for chemical experiments (mean + SD), values are normalized to the mean control of each experiment. For multi-group comparisons Dunn’s multiple-comparison post-test was used: *P < 0.05, **P ≤ 0.01, ***P ≤ 0.001
