Scale-up of bubble column photobioreactors for astaxanthin production

초록

Microalgae are the major primary producers of organic matters in aquatic environments through their photosynthetic activities. Dozens of microalgal species are produced commercially for single-cell protein, polysaccharides, health food compounds such as polyunsaturated fatty acids, and vitamins in the pharmaceutical and dietetic industry. Recently Haematococcus pluvialis is widely studied as one of the best sources of astaxanthin(3,3'-dihydroxy-b,b'-carotene-dione), a ketocarotenoid pigment with potential effects of cancer prevention, enhancer of immune response, and a free radial quencher.
