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.
