PROCESSES FOR IN VIVO PRODUCTION OF ASTAXANTHIN AND PHAFFIA RHODOZYMA YEAST OF ENHANCED ASTAXANTHIN CONTENT

摘要

An economical process for the in vitro production ofcarotenoids, particularly the pigment astaxanthin, andparticularly a process for enhancing astaxanthin content ofcultures of microorganisms of genus Phaffia, the processcomprising culturing a microorganism of genus Phaffia in anutrient medium containing an antibiotic, cytochrome Binhibitor, or a terpenoid synthetic pathway inhibitor, orsubjecting said microorganism to growth in the presence of ametabolic pathway inhibitor, particularly a main respiratorypathway inhibitor, in the presence of an influence whichtriggers a secondary respiratory pathway.
