  1. Biofilms were formed in polystyrene plates and data are shown as mean log10 CFU per well (±the standard errors of the means). The influence of disinfectants on biofilms was determined by enumerating viable cells remaining after treatment with 1% Topactive Des., 0.45% Kwiksan 22 (QAC) and 1% Profoam (QAC) treatment and compared to that of PBS control
