It illustrates microorganism control measures in bottle-packed pure drinking water production,introduces microorganism index control by ozone sterilization from the creation of ozone,its mixing with pure water,sterilization effect and its influential matters,which to give certain guidance for actual production.

The sterilization effect of high-intensity pulsed magnetic field (PMF) on bacteria was studied.

Using Escherichia coli as the object microorganism,the influence of different growth phase of Escherichia coli,magnetic field intensity,pulsed number of magnetic field and material temperature on sterilization effect was studied.

This paper discusses an experimental study for improving the germicidal efficacy of stabilized chlorine dioxide by orthogonal trial method.

Objective To know the germicidal efficacy and toxicity of a herb antibacterial lotion.

Objective To observe the effective of activating conditions on germicidal efficacy of chlorine dioxide.

In order to improve biological control efficacy of Bacillus subtilis to apple anthracnose,by means of bioassay method,the mechanisms of action and efficacy of Bacillus subtilis strain BS80-6,screened by ion implantation,against apple anthracnose caused by Colletotrichum gloeosporioides were studied in vitro and on apples,in different conditions.

Activities of the cell wall degrading enzymes(CWDEs) produced by Colletotrichum gloeosporioides both in vitro and in vivo were studied.

Apple anthracnose caused by Colletotrichum gloeosporioides has been an important disease of postharvest apple, which caused fruit rot during storage.
