Photomixotrophic cultivation of algae Euglena gracilis in photobioreactor

In the future, due to limited resources a crisis of energy storing molecules (fuels), which are currently produced from crude mineral oil, is expected. One strategy to compensate a part of the oil deficiency is the production of biodiesel from microalgae lipid. In this research, algae Euglena gracilis was chosen as model microorganism for lipid production. Photomixotrophic cultivation was done in self-constructed photobioreactor. During cultivation, chlorophyl, vitamine (E, A), biomass, substarte and cultivation conditions (temperature, pH, rpm, pO_2, CO_2, hν) were monitored. Due to the optimization of medium composition and cultivation conditions, lipid production was increased from 0.4 % to 60 % of biomass dry weight. Promising results obtained in this reserch encouraged us for futher investigation.
