Survival curve of biofilm treated with 20 kHz plasma.

Abstract

<p>48-hour <i>P. aeruginosa</i> biofilms, grown on Calgary Biofilm Device, were exposed to the 20 kHz plasma jet for up to 4 minutes. The number of biofilm surviving cells in each sample was then calculated using colony count method and used to construct the log survival curve. (Each point represents the mean of 3 values ± SE).</p
