為什么開水容易滋生細菌?
|

看一個視頻,開水對比冷水,室內(nèi)開口放置24小時。檢測,開水的細菌量涂片全滿,冷水也有細菌,只是少量 為什么開水更容易滋生細菌? |

I can come up with only 2 factors: 1, Temperature: In the cooling down process of the boiled water, temperature decreases to a certain threshold that is favorable for the growth of microbial. 2, Ions: some ions in water aggregated together when the water is boiling, less ions may lead to less hazard environment for bacteria |

Cl2 and ClO2 are the common reagents, which used to keep drinking water microbes free. The boiling process destroy these reagents. 發(fā)自小木蟲Android客戶端 |

開水沒有優(yōu)勢菌群了吧,冷水中的優(yōu)勢菌群會抑制其他菌類的生長,但是開水中是一個開放的環(huán)境,弱勢菌群也可以和其他菌群一同生長 發(fā)自小木蟲Android客戶端 |
