Inactivation Dynamics of TMV under Different Water Bodies and Temperatures

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.
