Effects of different cold atmospheric‐pressure plasma sources on the yeast Candida glabrata.

Four different cold plasma sources were directly applied onto a 24h inoculum of Candida glabrata inoculated on agar plates, within the limits of in vitro experiment. Their effects were compared and evaluated with respect to the size and stability of the inhibition zones formed in the posttreatment cultivation. The results prove significant inhibitory cold atmospheric‐pressure plasma effects on the yeast C. glabrata. The overall inhibitory effects are directly proportional to the treatment time, the applied power, and the overall functioning of the plasma source and indirectly proportional to the initial cell concentration, although this factor was less significant compared to the other examined factors. The unipolar microwave torch was found to be the most effective in the inhibition of C. glabrata. [ABSTRACT FROM AUTHOR]
