| Abstract: | Summary Growth parameters of Catharanthus roseus in suspension cultures were examined under various pCO2 conditions. In CO2-enriched environments (up to 2 %) for Erlenmeyer flask cultures, enhanced maximum growth rates and conversion yields were observed. Fermenter cultures with a constant pCO2 of 2 %, gave high conversion yields although no growth-promoting activity was observed. High aeration rates led to decreased rates of growth due to CO2 stripping. |
