Impact of bacteriophages on wastewater treatment processes and their application

研究了噬菌体对废水处理的影响，以及噬菌体分析方法的发展。在噬菌体裂解产物中检测到宿主DNA，这一发现为通过分析污水处理过程中上清液中的DNA来鉴定裂解宿主提供了可能性。据估计，每天大约有1%到几%的细菌被噬菌体裂解，利用噬菌体来减少废弃污泥是可能的。噬菌体DNA不能被限制性内切酶消化，表明噬菌体与宿主之间存在复杂的关系。然而，仍然需要进一步汇编案例研究，以了解噬菌体对废水处理的影响。

The influence of bacteriophages on wastewater treatment was investigated, together with the development of methods to analyze bacteriophages. Host DNA was detected in the lysate of phages, and the finding lead to the possibility to identify the lysed host by analyzing DNA in supernatant of wastewater treatment processes. It was estimated that around 1 to several % of bacteria are daily lysed by phages, and it may be possible to use phages to reduce waste sludge. Phage DNA was resistant to digestion by restriction enzymes, suggesting the complex relationship between phages and host. Yet, further compilation of case studies is still needed to know the impact of phages on wastewater treatment.
