摘要

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 theeconomic feasibility of the underlying processes the yeast Rhodotorula glutinis was selected, as it is capable ofproducing not only lipids, but also carotenoids. The latter can be seen as a valuable by-product, which can increasethe economic feasibility. The carotenoid of the highest interest is β-carotene. Regarding the lipids, the fatty acidcomposition is of importance for the properties of producible biodiesel. In this experiment the effects of threedifferent C/N ratios (20:1, 70:1 and 120:1) of an artificially produced growth media after 216 hours of incubationwere investigated. The results show, that the C/N ratio is able to influence the composition of the microbial lipids.Regarding the total amount of carotenoids produced, only a tendency was visible. This however was not the case forβ-carotene concentration. Further research has to be conducted, to see if the obtained results can be converted to theuse of low cost substrates (e.g. municipal wastes, sewage sludge, wastes originating from agro-industry or foodindustry) as feedstock for Rhodotorula glutinis.
