摘要
通过实验室和现扬研究,证明沼气发酵对灭活脊髓灰质炎Ⅰ型病毒有一定效果。在实验室25℃、30℃、35℃下,分别发酵培育到第9、15、17天,投入的病毒就可全部灭活,而在营养对照液中三种温度下,直到第24天毒性仍不能测出终点;在现场沼气池发酵实验中,投入病毒发酵到第3天和第1天失活率就分别达94.75％和94.11％,在露天粪缸中到第9天,病毒失活率才达96％,而在营养对照液中,到第24天仅有66.88%失活。
Both laboratory and field observations confirmed the effect of fermentataion on killing poliovirus Ⅰ, During the process of fermentation in laboratory, all of three experimental groups fo poliovirus I had been killed by the 9th, 15th and 17th day respectively at 25℃, 30℃ and 35℃ relevantly. But in the control group there still were some polioviruses to be found on the 24th day. In two fermntation tanks in the field, the fatality rate of the same virus on the 3th and 1st day reached 94.75% and 94.11% resqeectively, but in open-air manure vat, 96% of fatality rate just appeared on the 9th day and only 66.88% on the 24th day in the control group.
