... The ammonia thus produced is oxidized to NO 2 - and then to NO 3 - by nitrite and nitrate bacteria in the soil using O 2 as an oxidizing agent (nitrification, Table 1). These bacteria are autotrophs that use inorganic nitrogen compounds as their energy source and fix carbon dioxide (chemosynthesis) using the energy generated by the oxidation reaction. Nitrite and nitrate bacteria are collectively called nitrifying bacteria, and these two groups of bacteria live ecologically in tandem. ... *Some of the terminology that mentions "chemosynthesis" is listed below.

… こうして生じたアンモニアは,土壌中の亜硝酸菌と硝酸菌によりO2を酸化剤として,NO2-を経てNO3-へと酸化される(硝化作用nitrification,表1)。これらの細菌は,無機窒素化合物をエネルギー源とし,その酸化反応で発生するエネルギーを利用して,炭酸固定を行う(化学合成chemosynthesis)独立栄養生物である。亜硝酸細菌と硝酸細菌は硝化細菌nitrifying bacteriaと総称され,この2群の細菌は生態学的に相伴って生息している。… ※「chemosynthesis」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
