Bioactive molecules from microalgae

The highly diverse group of microalgae offers a huge variety of bioactive molecules. Manipulation of culture conditions for microalgae allows for maximizing the yield of the desired component. Long-chain polyunsaturated fatty acids are important for the development of the human nervous system. Sterols can diminish cardiovascular disease risk factors. Polysaccharides can modulate the immune system, alleviate allergies, and serve as lubricants for damaged joints. The amino acid profile of microalgae protein is of high quality, and peptides derived from it allow pharmaceutical applications. Pigments such as carotenoids are powerful antioxidants and important for eyesight. Theoretically, yields can further be increased by genetic manipulation.
