シュードモナス属など数種を使って、窒素を抜く(?)ということが書いてあるのではないか。
とまでは辞書で訳して見たのですが、辞書にも載っていない単語(heterotrophicallyなど)に阻まれて全体を理解するには至りません。
これは冒頭部分なのですが、どういうことが書いてあるのか教えて下さい。
全訳でも嬉しいですが、説明を頂きたいです。
Heterotrophic Nitrification Among Denitrifiers
Twelve denitrifying bacteria representing six genera were tested for an ability to nitrify pyruvic oxime heterotrophically.
Six of these bacteria exhibited appreciable nitrification activity, yielding as much as 5.8 mM nitrite and little or no nitrate when grown in a mineral salts medium containing 7mM pyruvic oxime and 0.05% yeast extract.
Of the six active bacteria, four (Pseudomonas denitrificans, Pseudomonas aeruginosa, and two strains of Pseudomonas fluorescens) could grow slowly on pyruvic oxime, and one (Alcaligenes faecalis) could apparently row on pyruvic oxime in the presence of yeast extract but not in its absence.
Eight of the twelve bacteria in the resting state could oxidize hydroxylamine to nitrite, and P.aureofaciens was remarkably active in this regard.
In general, those denitrifiers active in the nitrification of pyruvic oxime or hydroxylamine or both are abundant in soils.
A possible advantage of having nitrification and denitrification capabilities in the same organism is discussed.
