Bacterial growth inhibition zones.

Abstract

<p><i>P. aeruginosa</i> cell suspensions were spread over MHA plates (9 cm in diameter). The seeded plates were exposed to the 20 kHz plasma jet for (A) 0 s, (B) 120 s, and (C) 240 s and then incubated at 37°C for 24 hours. After incubation, photographs of agar plates, showing bacterial growth inhibition zones, were taken using a digital camera.</p
