Summary Removal of gaseous metabolites in an aerated fermenter affects ajmalicine production by Catharanthus roseus negatively. Therefore, the role of CO2 and ethylene in ajmalicine production by C. roseus was investigated in 3 l fermenters (working volume 1.8 l) with recirculation of a large part of the exhaust air. Removal of CO2, ethylene or both from the recirculation stream did not have an effect on ajmalicine production. Inhibition of ethylene biosynthesis in shake flasks with Co2+, Ni2+ or aminooxyacetic acid did not affect ajmalicine production. However, the removal of CO2 did enhance the amount of extracellular ajmalicine.
