关于《微生物学》中微生物生长的控制——Eutrema wasabi杀细菌作用的研究

Research of the Eutrema wasabi to Several Pathogenic Bacteria Affects——The Control Growth of the Microorganisms in the Microbiology

微生物学中微生物生长的控制是人们研究的重要内容。利用Eutramawasabi提取物对几种细菌的致死作用进行了研究,Eutramawasabi处理细菌后,用平板菌落计数法测定杀菌率。结果表明,Eutremawasabi对病原菌有明显的杀灭作用。在Eutramawasabi提取物有效成分为0.5%～0.8%,作用时间为90～120min的条件下,对几种病原菌的杀菌率为80%～97%。这对控制微生物生长和杀灭有害病原菌找到了一条新途径;对防治病原菌的传播、保证人类健康、丰富微生物学教学内容都有积极意义。

The control growth of the microorganisms is an important research content in the microbiology. This paper repots an extract materials from the Eutrema wasabi to disinfect pathogenic bacteria affects,and to test disinfection bacteria rate using plate colong counting method.The result shows that consistency of the extract materials from the wasabi is 0.5%～0.8% ,times is 90～120min ,efficincy of wasabi to disinfect pathogenic bacteria is 80%～97% . A new scientific method has been found to disinfect pathogenic bacteria.It has positive significance for the prevention about disease ,making a public health,defending people's health and enriching the teaching work in microbiology.
