Получены воздушные плазменные струи атмосферного давления на постоянном, импульсно-периодическом и автоколебательном токовых режимах. Показано, что основным механизмом инактивации бактерий Staphylococcus aureus является воздействие химически активных молекул NO, NO2 и HNO2. Методом ИК-абсорбционной спектроскопии определены их концентрации. Выявлен оптимальный режим разряда, индуцирующий плазменные струи, наиболее подходящий для получения бактерицидных компонент. 

Atmospheric pressure air plasma jets within dc, pulsed and self-oscillatory current regimes are realized. It is shown that the main mechanism of inactivation of bacteria Staphylococcus aureus is the effect of chemically active molecules of NO, NO2 and HNO2. The method of IR absorption spectroscopy is used to investigate chemical active component concentrations. The optimal regime of discharge inducing plasma jets, which is more suitable for production of bactericidal components, is found.
