Percentage cell reduction curves based on colony count method vs. XTT assay.

Abstract

<p>Percentage cell reduction curves of <i>P. </i>aeruginosa biofilm cells upon exposure to the 20 kHz plasma jet. The dotted line is based on the standard colony count method whereas the solid line is based on the XTT assay. (Each point represents the mean of 3 values ± SE).</p
