【100年三等環化-硝化菌】
題目:何謂自營性硝化細菌?何謂異營性硝化細菌?
那一種是環境中主要之硝化細菌?為什麼?
主要之硝化細菌有那些?(15分)
想法:
1.「自營性硝化細菌」與「異營性硝化細菌」的定義大概知道。
2. 想要請教的是:
大致上知道環境中主要的硝化細菌:「自營性硝化細菌」,
但是問到「為什麼」時?寫不太出來
3.目前是想到自營菌所需要的能量較少,故環境中存在較多?
不過,總是覺得懷疑是這樣嗎?還是要怎麼回答會更切題呢?
有請板上各位先進不吝指正與指導,謝謝您 ^^

推 dunhilln:剛翻書本 硝化菌自然界自營性為主 異營性低pH時優勢 04/11 17:37
→ dunhilln:脫硝菌異營為主 我想題目問的跟pH有關係吧 04/11 17:37
→ dunhilln:謝謝你讓我去翻書 又加深印象了XD 04/11 17:37
→ alaninewu:自營的化學能較容易獲得吧 04/12 00:35
→ sandy18932:謝謝alaninewu大與dunhilln大的回應 ^^~ 04/12 07:44
推 totom:d兄說的沒錯,自營性和異營性硝化菌,誰為優勢,是因pH值 04/12 23:13
→ totom:pH較低時,自營菌不易生存,某些異營菌可進行硝化作用(背) 04/12 23:15
