Abstract: The present invention is related to a novel enzymatic process for production of vitamin A aldehyde (retinal) via stereoselective conversion of beta-carotene which process includes the use of trans-selective enzymes having activity as beta-carotene oxidases (BCOs), in particular having preference for trans-retinal. 5 Said process is in particular useful for biotechnological production of vitamin A.

Abstract: The present invention is related to a novel enzymatic process for production of vitamin A alcohol (retinol) via conversion of retinal, which process includes the use of heterologous enzymes having activity as retinal reductase, particularly wherein the reaction leads to at least about 90% conversion of retinal into retinol. Said process is particularly useful for biotechnological production of vitamin A.

Abstract: The present invention is related to a novel enzymatic process for production of retinoids via a multi-step process, which process includes the use of heterologous enzymes having activity in a carotene-producing host cell, particularly wherein such process results in high percentage of retinoids, in trans-isoform.

IPC: C12P23/00

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.
