Inactivation effects of nitrogen plasma and carbon dioxide plasma on <i>P</i>. <i>aeruginosa</i> suspension including each radical scavenger.

<p>(Treatment time, 60 s; initial bacteria concentration, 5.4 × 10⁷ CFU). SOD was used as a superoxide scavenger, catalase as a H₂O₂ scavenger, NaN₃ as a singlet oxygen scavenger, and DMSO as an OH radical scavenger.</p
