| 摘 要： | 文章以小球藻和纤细裸藻为对象,研究了以三氯生作为主要灭菌剂的某复方洗手消毒液对其生物量和叶绿素荧光指数Fv/Fm 的影响。结果显示:洗手液浓度大于01 mL/L时对小球藻的生长有抑制作用,大于02mL/L时小球藻的PSⅡ反应中心受到胁迫,且Fv/Fm无法恢复到正常水平;洗手液浓度大于0.2mL/L时对纤细裸藻的生长有抑...

| Abstract: | Effect of a compound hand-washing disinfectant solution on Chlorella vulgaris and Euglena gracilis was investigated by detecting its biomass and chlorophyll fluorescence index Fv/Fm.Result turned out that it showed inhibitional effect on Chlorella vulgaris with concentration more than 0.1mL/L,Euglena gracilis with concentration more than 0.2 mL/L. When the concentration exceeded 0.2 mL/L,the PSⅡreactive center of Chlorella vulgaris was compelled and Fv/Fm couldn't be restored to the normal level,while the PSⅡreactive center of Euglena gracilis could restore to the normal level under the testing concentration,which demonstrated that Euglena gracilis is more tolerant than Chlorella vulgaris,the hand sanitizer could have certain effect on algae species when discharged into water. |
