Dispersal of Salmonella biofilms by diethylamine NONOate sodium salt. Biofilms were formed overnight by either S. enterica sv. Typhimurium ATCC14028 or a cocktail of six Salmonella enterica strains (sv. Braenderup 04E01347, Braenderup 04E01556, Braenderup 04E00783, sv. Montevideo LJH519, sv. Javiana ATCC BAA-1593 and sv. Newport C6.3) linked to produce-associated outbreaks of gastroenteritis. Biofilms were pre-formed on either polystyrene (black bars) or polypropylene (grey bars) prior to the treatment with diethylamine NONOate sodium salt. Concentrations of the nitric oxide donor are on the x-axis. Contact time and temperature at which the treatment took place are indicated above each panel. Residual biofilms were quantified by staining with crystal violet. Error bars are standard errors.
