    • Centrifuged supernatant was subjected to analytical HPLC with TOSOH TSK-gel ODS-100S (4.6 mm i.d. × 150 mm; solvent A, acetonitrile containing 0.5% acetic acid; solvent B, 0.5% aq acetic acid; gradient profile, 0-5 min 35% A, 5-30 min 35-95% A, 30-35 min 95% A, 35-40 min 95-35%A; flow rate, 1.0 mL/min; temperature, 40 °C). The LC condition for LC/ESI-MS was the same as that of analytical HPLC.

    • 4 (1/20 vol) was added dropwise. The reaction mixture was heated under reflux for 2 h. Water (1 vol) was added and the mixture was concentrated in vacuo. The resultant suspension was extracted with EtOAc, and EtOAc removed in vacuo. The residue was subjected to a silica gel column chromatography.

    • The seed culture was transferred to 100 mL each of R4 medium in 500 mL Erlenmyer flasks (total 2.0 L), which were grown shaking (200 rpm) at 28 °C. An aqueous solution of the labeled acetic acid (200 mg/mL) was sterilized by 0.22 μm pore filter. Aliquots (100 μL) of the solution (containing 20 mg of acetic acid) were added to each flask of a 2-day culture followed by fermentation for further 3 days.
