  • Publication number: 20200239925
    Abstract: The present invention is related to production of retinyl esters, such as in particular retinyl acetate, an important building block for production of vitamin A. The retinyl esters might be generated via enzymatic conversion of retinol which process includes the use of enzymes with acetyl-transferase (ATF) activity, thus acetylating retinol into retinol/retinyl acetate. Said process is particularly useful for biotechnological production of vitamin A.
