本文研究发现噬菌蛭弧菌Bd81对河水中大肠菌群具有显著的净化效果,检测试验组和对照组Ⅰ的河水中大肠菌群21天时,由2.38×10~7个/L减少到2.3×10~3个/L,而对照组Ⅱ仅由2.38×10~6个/L减少到2.38×10~4个/L。同时,噬菌蛭弧菌Bd81却增殖7～10倍。河水的浊度、生物耗氧量、Ca~(++)、Mg~(++)、总硬度、氯化物、pH等指标也发生了变化。与对照组比较有显著性差异。
In this study, we found that Bdellicobutius Bdellovibrio Bd81 has a significant purification effect on coliform bacteria in river water. When the coliform bacteria in river water of test group I and control group I were reduced by 21.3 days from 2.38 × 10-7 / L to 2.3 × 10 ~ 3 / L, while the control group Ⅱ only reduced from 2.38 × 10 ~ 6 / L to 2.38 × 10 ~ 4 / L. At the same time, Bdellovibrio Bdellii B71 but proliferate 7 to 10 times. Water turbidity, biological oxygen consumption, Ca ~ (++), Mg ~ (++), total hardness, chloride, pH and other indicators also changed. Compared with the control group, there are significant differences.
