Abstract
Zeaxanthin is produced using Flavobacterium multivorum. The process and the nutrient medium used in the process provide greater zeaxanthin and cell yields per liter, at a lower cost, and more rapidly than known methods and microorganisms. Biomass compositions containing the microorganism of this invention are also disclosed.
Claims19
A process for the production of zeaxanthin comprising:
- culturing a strain of pigmented Flavobacterium multivorum in a nutrient medium that comprises at least one assimilable carbon source, and at least one assimilable nitrogen source, and
- recovering zeaxanthin from the culture.
A process for the preparation of zeaxanthin comprising:
- culturing a strain of Flavobacterium multivorum in a medium comprising about 4.0% to about 8.0% corn steep liquor, about 3.0% to about 5.0% corn flour, about 1.0% fat and about 0.1 ml/l amylase, and recovering the zeaxanthin therefrom.
