Previously, Su et al. [Biotechnol Bioeng 42: 884–890 (1993)] reported improved production of rosmarinic acid by Anchusa officinalis in shakeflask cultures using a cultivation strategy that involved intermittent medium exchange. Implementation of this cultivation strategy in stirredtank bioreactor cultures is investigated in the present study.
