式の説明が出てきて、単語の意味が判らなくなります。
下手な文ですみませんが、見てください。
Then Eq(2-20) may be split into two equations, one for the forward reaction and another for reverse reaction, which will have a difference in agreement with (2-21):
そして、式(２－２０)は正反応のためのものと逆反応のための別のものとに式(２－２１)の一致とは異なり、分かれているかも知れません。
（２-２２） d(lnk2)/dＴ＝ΔＨ2/(ＲgＴ^2)
（２-２３） d(lnk'1)/dＴ＝ΔＨ1/(ＲgＴ^2)
An alternate derivation is based on the concept of an intermediate state, often called a transition or activated state, which is a postulate of the transition-state theory (Sec2-26).
●交替の派生は、遷移状態 しばしば遷移または遷移状態の理論で活性化状態と呼ばれる の理論に基づきます。
Suppose that product C of the reaction
もし反応の生成物がCならば
（２-２５） Ａ＋Ｂ→Ｃ
is formed by decomposition of an activated form of reactants A and B, which will be designated (AB)*.
(AB)*と称される反応物AとBの活性化した形の分解を形成します。
Then the reaction occurs by two elementary steps,
そして、反応は２つの素過程で起こります。
If the first step is comparatively rapid in both forward and reverse directions, (AB)* will be in equilibrium with A and B so that its concentration is given by
●もし正と逆の方向において第一段階がかなり急速で、過ぎてその濃度が与えられるように、(AB)*がAとBによって平衡にあるならば
（２-２８） Ｃ{AB*}＝Ｋ*Ｃ{A}Ｃ{B}
where K* is the equilibrium constant for the formation of (AB)* .
ｋ*が(AB)*の形成のための平衡定数である。
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.
