METHOD TO PRODUCE RETINYL ACETATE

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, wherein the product purity could be increased with reduction of unwanted side-products. Particularly, the novel process comprises fermentation in...

Beschreibung
Zusammenfassung:	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, wherein the product purity could be increased with reduction of unwanted side-products. Particularly, the novel process comprises fermentation in the presence of ethanol, such as e.g. in a fed-batch fermentation process. Such process is especially useful in a biotechnological process for production of vitamin A.
