  • REDUCTION OF FATTY ACID RETINYL ESTER FORMATION
    Publication number: 20230265443
    Abstract: The present invention is related to a novel process for production of retinyl acetate in a host cell, particularly oleaginous yeast such as e.g. Yarrowia, growing on triglyceride oils, such as e.g. vegetable oil, wherein the host cell exhibits modified lipase activity in such a way that conversion of retinol into fatty acid retinyl esters (FAREs) is reduced or abolished. Such process is especially useful in a biotechnological process for production of vitamin A.
