A: HPLC-MS chromatogram obtained after MRM analysis of the flavonols extracted from S. coelicolor-pMYR. The peaks correspond to myricetin (MYR: <0.1 μM), dihydrokaempferol (DHK: <0.1 μM) and quercetin (QR: <0.1 μM). B: chromatogram obtained after MRM analysis of the flavonols extracted from S. albus-pMYR. The peaks correspond to myricetin (MYR: 0.146 μM), dihydrokaempferol (DHK: 0.024 μM), quercetin (QR: 1.984 μM) and kaempferol (KF: 0.034 μM). C: chromatogram obtained from extracts of S. albus-pMYR-pREC4. The peaks correspond to apigenin (0.3 μM) and luteolin (below 0.1 μM).
