Versuchsvorschrift
We also performed the shake flask experiments in LB medium, under the same conditions as described for the M9 medium. When p-coumaric acid was used as a precursor, naringenin (0.39 mg/lt) and dihydrokaempferol (1.29 mg/lt) accumulated in the fermentation broth but no kaempferol was produced. When caffeic acid was used as a precursor, eriodictyol accumulated at a lower concentration compared to the M9 medium (7.5 μg/lt), while no dihydroquercetin or quercetin was detected. Finally, when cinnamic acid was used, pinocembrin accumulated at a concentration of 0.245 mg/lt and no dihydroflavonol or flavonol was detected.
