摘要

了解植物病毒在不同水体与温度条件下的灭活规律具有重要的理论与实际意义。本文以典型植物病毒烟草花叶病毒（TMV）为模型，比较了其在不同温度条件下，在闽江水、自来水、生活污水、微孔滤膜过滤除菌污水及超纯水中的灭活动力学。结果显示，温度是导致TMV灭活的重要因素，水温升高，病毒灭活速率加快；此外，某些水质因子也影响TMV的灭活效率，其中可溶性盐的存在及其含量对TMV的灭活会因所处的环境不同而异；某些微生物或代谢产物对植物病毒TMV具有灭活作用，而能生化降解的有机质加速TMV灭活可能是通过促进水体中的微生物增殖而起作用。

Abstract

It is very important to understand the laws of Tobacco mosaic virus(TMV) inactivation under different water bodies and temperatures. Choosing the typical plant virus TMV as a model virus, the inactivation dynamics of it in Min River water, tap water, super-pure water, life sewage and sterile sewage under different temperatures were studied in this paper. The results showed that the temperature was a very important factor to influence the survival of TMV. The higher temperature of the water body, the faster the inactivation rate of TMV. Besides the environmental temperature, some water quality factors also influence the inactivation rate of TMV. The influences of the dissolved salts on the inactivation of TMV were different from the various environmental conditions. Some microbes or their metabolites were harmful to the survival of TMV. The biodegradable organic substances lead to TMV inactivation may be throught to promote the bacteria multiplying.
