| 摘 要： | 用生长速率测定法研究了ＺｎＳ胶体光诱导的抑菌（ｂａｃｔｅｒｉｏｓｔａｓｉｓ）作用。实验结果表明，ＺｎＳ胶体在光照时能够明显地抑制大丽菊轮枝霉（ＶｅｒｔｉｃｉｌｌｉｕｍＤａｈｌｉａｅ）的生长，而在不光照时没有这一效果。其原因是ＺｎＳ胶体在光激发下能够生成大量的活性氧自由基。在本文实验条件下ＺｎＳ胶体的半致死浓度（ＬＣ５０）是４．３３×１０－５ｍｏｌ／Ｌ。

| Abstract: | The photoinduced bacteriostasis effect of ZnS colloid was studied with using growth rate method. It was observed that ZnS colloid can inhibit the growth of Verticillium Dahliae obvisouly under irradiation, but it loses this fuction in dark. The reason may be a great amount of active oxygen was generated when ZnS was actived by light. In the condition of this article, the medium lethal concentration(LC50) of ZnS colloid is 4. 33×10-5mol/L. |
