The purpose of study:to research the influence of nonequlibrium cold argon

nonequlibrium cold argon plasma on Escherichia coli and natural

association of microorganisms
The objectives:
1. To analyze microorganisms` sensitivity to the treatment by means of cold argon plasma;
2. To identify optimum condition for microorganisms` inactivation.

Institute of physical materials SB RAMS

The objects of study:
- Vegetative form of Escherichia coli (strain М17)
- Natural association of microorganisms


Слайд 6 Inactivation`s zones of bacterial growth natural association of

Inactivation`s zones of bacterial growth natural association of microorganisms caused by

microorganisms caused by plasma`s influence
inactivation zone`s diameter – contact

time relationship

(a) – t=10 сек, (f) – t = 60 сек

In conclusion:The high sensitivity of Escherichia coli and natural association of

natural association of microorganisms to the treatment by cold

argon plasma was proved.
Optimized conditions of treatment by plasma : the time – 60 с.; I = 500 мкА; h - 0,5 см.
