Virus loss in activated sludge appeared to be caused by microorganisms. This conclusion is supported by the finding that poliovirus infectivity decreased during incubation in mixed-liquor suspended solids, primarily because of a sedimentable, heat-sensitive component. Furthermore, broth spiked with mixed-liquor suspended solids acquired antiviral activity during incubation.
活性污泥中的病毒损失似乎是由微生物引起的。这一结论得到了以下发现的支持:脊髓灰质炎病毒在混合液悬浮固体中培养期间感染力下降,主要是由于一种可沉淀的、对热敏感的成分。此外,加入混合液悬浮固体的肉汤在培养期间获得了抗病毒活性。
