Název v původním jazyce

Active but nonculturable state of Escherichia coli induced by plasma generated in gas and liquid phase

Popis výsledku v původním jazyce

Non-thermal atmospheric pressure plasma is extensively applied as an efficient decontamination medium; however, the decontamination is usually evaluated by the simplest classical cultivation method. We investigated the plasma induced inactivation by theconventional cultivation and fluorescent LIVE/DEAD BacLight Bacterial Viability techniques. The decontamination effect was studied on a culture of Escherichia coli deposited either on a solid surface or dispersed in a saline solution. We observed that the bacterial counts decreased with increasing treatment time of atmospheric pressure plasma jet and coplanar surface dielectric barrier discharge. We assume that interaction of plasma with bacteria induces a stress which does not lead to the death of bacteria, but to the loss of their ability to be cultivated, thus viable but nonculturable state (VBNC) occurs.
