Abstract
A process for the preparation of zeaxanthin which comprises culturing a microorganism of the genus Flavobacter producing this pigment in a nutrient medium containing at least one carbohydrate as assimilable carbon source, at least one source of assimilable amino nitrogen containing free amino acids, mineral salts, oligoelements and vitamins, the composition of the medium being modified by adding pyridoxine to it, and continuing culturing until a substantial quantity of intracellular zeaxanthin has been obtained.
