Zusammenfassung:The present invention provides an optimized method of continuously culturing an auxotrophic marine microorganism in a fermentor under aerobic conditions at Y g/l of cell dry matter, CDM, wherein Y is in the range from 100-300 g/l, comprising culturing said auxotrophic marine microorganism in a culture medium comprising a carbon source, gradually added, in an amount of (Yxh) gram per litre of culture broth, wherein h is in the range from 1.1-3.0, and with a residence time of 20-100 h. The method maintains a high productivity of cellular lipids, especially polyenoic acids.
