The examination of influence of ozonized solutions on microorganisms in defined conditions needs continuation. They were alive, even after 30 minutes of incubation in freshly ozonized water. Detailed results of the test are presented szzmal Table 2. Then it was applied in the biocidal assay with 1 min. The aim of this study was to analyse basic bactericidal and fungicidal activity of ozonized water and saline solution, according to European validated.

The suitability of ozone therapy is also indicated by the fact that its antibacterial, antifungal and antiviral activity is accompanied by a number of other biologically positive effects, such as: Moreover, the method of ozone application is also cost-efficient, shortens the duration of required antibiotic therapy, and is sometimes the only available auxiliary technique to support surgical procedures.
These mixtures could be used as effective antiseptic and disinfection preparations. It means that prepared ozonized solutions complied with the requirements of EN Standards: Zsmal abstracts Search again.
All cells of S. During second step of experiments, when ozonization of water was completed, solutions were kept for 30 min in room temp. Antimicrobial activity of ozone is widely known and such attribute may sometimes be utilized e.
The renewed interest in ozone therapy, apart from this basic function, is also the result of several other factors, of which the most important are: Test was performed according to the method described in a handbook for pharmacy students written by Zdzis;aw Stefan Szmal and Tadeusz Lipiec: The ozone concentration was in the range: Efficacy of action against Aspergillus niger spores required longer contact time, than against bacterial cells or vegetative cells of yeast.
It was shown, that very short contact time – even 30 seconds, caused at Sample 2: The decimal logarithm of reduction was over 5,3.
The ozone concentration in used solutions were in the range: An archive of our older newsletters dating back to can be found here. Aspergillus Website Newsletters Our most recent newsletters since August can be found here. Chemically obtained data were compared with antimicrobial effects.
The ozone concentration in ozonized solutions was sufficient to kill all cells of tested bacterial and yeast strains after a very short contact time – 30 seconds.

In this case the ozone concentration in ozonized water was in the range: The products comply with the requirements mentioned in above EN Standards, when demonstrate at least 5 decimal log reduction of viable bacterial cells count and at least 4 decimal log reduction of viable fungal cells count.
Ozone concentration in tested liquids was also determined by titration. Most of the tests were performed using ozonized water.
Fill out your e-mail address to receive our newsletter! Different contact times and concentration of ozone were applied and log reduction factors of viable bacteria count and viable yeast and mould count were calculated.
The following 4 standard bacterial strains were used: Our most recent newsletters since August can be found here. Skip to main content. The principle of this method contains two steps: However, in such application ozone concentration lipiiec rather low and bactericidal effects is not very high.
