Study on breeding and fermentation technology of microalgae docosahexaenoic acid strain

As a new generation of functional food and medicine health care factor, microalgae docosahexaenoic acid (DHA) has become a hotspot in global scientific research and industrial research. The breeding technology of strains is the premise and basis of DHA extraction of microalgae. Fermentation culture is the core technology that directly determines the yield of microalgae DHA. Therefore, it is important to study the breeding and fermentation culture techniques of microalgae DHA strains for the development of microalgae DHA. This paper mainly analyzed the technology chain of microalgae DHA strain breeding and fermentation culture, compared the advantages and disadvantages of various methods of microalgae DHA strain breeding, and studied the important techniques of strain breeding and fermentation culture, in order to provide relevant theoretical and technical basis for the optimization, innovation and development of microalgae DHA strain breeding and fermentation culture technology, thus effectively increasing the yield of microalgae DHA.
