From: Dispersal of human and plant pathogens biofilms via nitric oxide donors at 4 °C
Dispersal of different preformed biofilms by the nitric oxide donors SNAP, Noc-5 and NO-aspirin on polypropylene during exposure at 4 °C. Salmonella and E. coli cocktails: see “Materials and methods” section for details about the strains. Concentrations of the nitric oxide donor are on the x-axis. Residual biofilms were quantified by staining with crystal violet. Error bars are standard errors. Asterisk (*) represents significant different mean when compared with the PBS treatment only (p = 0.05)
