Abstract

A procedure for the preparation of zeaxanthin, characterized by cultivating a microorganism of the CBS 519/67 or CBS 523/67 races of the genus Flavobacter or a subculture of these races obtained by selection or mutation in an aqueous nutrient solution containing a carbon source assimilable and an assimilable nitrogen source, in addition to the usual additives in the fermentation processes, if desired with lighting and/or the addition of substances promoting pigment formation and growth and, if desired, by insulating from the mass cell obtained zeaxanthin.
