About the thesis
Marine cold-adapted microalgae are a promising bioresource to replace unsustainable fish oil or soybean-based proteins and their production does not compete with traditional agriculture for arable land. Even though low ambient temperatures at high latitudes (e.g., Northern Norway) are optimal for their cultivation, low solar irradiance limits photosynthesis and therefore expensive artificial light is needed. 

The thesis identified cold-adapted microalgae that grow fast at a temperature of 15°C or below and contain valuable polyunsaturated fatty acids, (PUFA), proteins or pigments that could be used as food or feed components. By optimising cultivation parameters such as temperature, light intensity and nutrient or salt supply, PUFA production could be greatly enhanced. 

Furthermore, a technological advance in microalgal cultivation was made through the application of light emitting diodes (LEDs) that periodically emit short but intense light pulses (i.e., flashing light). This alternative way of artificial light supply substantially improved PUFA or pigment production, compared to continuous light. 

Both the optimisation of cultivation conditions and the supply of flashing light will be key for high latitude production of cold-adapted microalgae rich in valuable biomolecules.
