Fossil fuels cannot be used endlessly, thus the interest in research for alternative biofuels has increased. This paper focuses on the production of 3rd generation biodiesel produced by yeasts. In order to increase the economic feasibility of the underlying processes the yeast Rhodotorula glutinis was selected, as it is capable of producing not only lipids, but also carotenoids. The latter can be seen as a valuable by¬product, which can increase the economic feasibility. The carotenoid...
