Therefore, the metabolic pathway from soybean oil to erythromycin was presumed as follows: soybean oil is metabolized into TCA pathway to generate much α ketoglutaric acid and then generate succinyl CoA by strengthening TCA pathway, and the methylmalonyl CoA is formed from succinyl CoA by isomerization. Finally, methylmalonyl CoA can be used as the precursor for the biosynthesis of erythromycin.

推测豆油经过红色糖多孢菌代谢后进入红霉素合成的一条可能途径：豆油经过代谢后进入TCA循环，并强化了TCA循环的通量，产生了大量α酮戊二酸，再生成琥珀酰CoA，琥珀酰CoA在甲基丙二酰CoA异构酶的作用下生成甲基丙二酰CoA作为红霉素合成的前体。

To summarize this new preliminary study, we have shown that the combination of Mn and Co is an efficient catalyst for the one-step aerobic oxidation of cyclohexane to adipic acid, displaying a much higher activity than Co and Mn alone.

总结这一新的初步研究，我们已经表明，相结合的锰和钴是一种有效的催化剂一步有氧氧化环己烷合成己二酸，展示了高得多的活性比钴和Mn独立。
