噬菌体MS2作为潜在的水中肠道病毒指示生物,已逐渐成为回用水微生物学安全评价指标的主要研究方向之一。测定了温度、pH值、紫外线和感染复数对噬菌体MS2活性的影响。结果表明：噬菌体MS2在70℃时5 min内即会全部失活,在pH值4～10的范围内均可稳定存在,在短波紫外线照射下25 min内即可失活;噬菌体MS2感染其宿主大肠杆菌的最佳感染复数为1。
噬菌體MS2作為潛在的水中腸道病毒指示生物,已逐漸成為迴用水微生物學安全評價指標的主要研究方嚮之一。測定瞭溫度、pH值、紫外線和感染複數對噬菌體MS2活性的影響。結果錶明：噬菌體MS2在70℃時5 min內即會全部失活,在pH值4～10的範圍內均可穩定存在,在短波紫外線照射下25 min內即可失活;噬菌體MS2感染其宿主大腸桿菌的最佳感染複數為1。
서균체MS2작위잠재적수중장도병독지시생물,이축점성위회용수미생물학안전평개지표적주요연구방향지일。측정료온도、pH치、자외선화감염복수대서균체MS2활성적영향。결과표명：서균체MS2재70℃시5 min내즉회전부실활,재pH치4～10적범위내균가은정존재,재단파자외선조사하25 min내즉가실활;서균체MS2감염기숙주대장간균적최가감염복수위1。
As an indicator of potential enterovirus,bacteriophage MS2 has become one of the most important research directions about the microbiological safety evaluation system for recycled wastewater.In this paper,survival rate of bacteriophage MS2 is determined in solutions with different temperature,pH,ultraviolet rays and infection multiplicity.The results showed that it can be inactivated completely when heating at 70℃ heating for 5 minutes.MS2 had relatively high stability at pH value of 4~10.MS2 was inactivated completely under ultraviolet rays for 25 minutes.The optimal multiplicity of infection was 1.
