PHAFFIA RHODOZYMA STRAINS HAVING A HIGH INTRACELLULAR CONCENTRATION OF ASTAXANHIN AND A LOW INTRACELLULAR CONCENTRATION OF HDCO

摘要

Invention relates to microbiological method of producing astaxanin by yeast Phaffia rhodozyma stems which produce astaxanin in high concentration simultaneously producing 3-oxy-3',4'-didehydro-beta,xi-caroten-4-one (HDCO) in low concentration.
