Process to produce astaxanthin from haematococcus biomass

摘要: This invention discloses a cyclic process for the production of astaxanthin rich biomass by cultivating Haematococcus algae. Modified nutrient medium containing 4 nitrogen sources is used culturing Green motile cells produced are converted into dormant red cysts which chilled and stressed vigorous multiplication. Nutrients added gradually initial germination carried out without carbon dioxide sparging. The dilution stage also effected in absence dioxide. regerminated cycle repeated to produce enriched with astaxanthin.
