ABSTRACT
Objective To develop a new method for sterilization in agars culture mediums,i.e.Agars culture mediums is sealed to be sterilized and preserved after resolution.Methods The effect of rudimental Ethylene Epoxide was investigated,and the germiculture results by different preserving methods were analyzed.Air sedimentation bacterium was sampled by different methods to analyze the bacterium capture rate.Results Ethylene Epoxide sterilized agars culture mediums bacterium capture rate was similar with regular agars.Conclusion Ethylene Epoxide sterilized agars culture mediums can be used in sampling of clinical treatment and other outburst incident,reducing the preparation time.
ABSTRACT
Objective To create a sterilized condition in field operation and the daily grind avoiding the intercross contamination between the experimentation and outside. Methods The air in the experimentation was filtrated by primary and advanced filter. High intense ultraviolet was used to sterilize the air, and negative compression was kept in the experiment condition. Results Hyperpurificatory biosafety cabinet guaranteed the sterilization condition in field operation and the daily grind, avoiding the intercross contamination. Conclusion Hyperpurificatory biosafety cabinet can be used in medical treatment, pharmacy, food industry, electrical industry, instrumentation, bioengineering, scientific tests, especially biology species identification in biological warfare.
