A plane plasma jet in the atmospheric pressure air was obtained. It had a width of 3 cm and a length of 4 cm. The plane plasma jet was formed in a single-barrier discharge with voltage pulse sharpening at low gas flow (1 l/min) in the slit geometry of the discharge zone. The plasma jet energy, temperature and spectral characteristics measurements were measured. It is shown that the radiation spectrum contains the intensive peaks corresponding to the vibrational transitions of the second positive system of molecular nitrogen N2 (C3Πu → B3Πg ) and the relatively weak transitions of the first positive system of the ion N2+ (B2Σ+u → Χ2Σg ). Using culture of Staphylococcus aureus (strain 209 ATSS) as an example, it is obtained that formed plasma is a source of chemical active particles, which ensure inactivation of microorganisms.
