ABSTRACT:
It is intended to provide a process for conveniently and efficiently producing large amounts of astaxanthin and canthaxanthin from a material which can be easily obtained. A microorganismThraustochytriumsp. CHN-3 (FERM P-18556) capable of producing astaxanthin and canthaxanthin, which belongs to the genusLabyrinthulaand theThraustochytriumspecies, is cultured and thus astaxanthin and canthaxanthin are accumulated in the microbial cells. Then the cells are separated from the medium and astaxanthin and canthaxanthin are collected from the separated cells by extracting with a solvent.
