to conversion liquid in the reactor. Three typical levels of gel beads to liquid ratio
(v/v), including 160:200, 120:200, and 80:200, were set to determine their effect
on CoQ10 yield in 360 mL total conversion volume in TPFBR at 30 ◦C and an aeration
rate of 0.3 L/min. The concentrations of CoQ10 and solanesol in the organic phase
and PHB in the aqueous phase were analyzed by HPLC after 8 h of conversion.
