Title:
METHOD FOR PRODUCING FERMENTED CAROTENOID USING CAROTENOID-PRODUCING BACTERIA OBTAINED BY USING COBALT-CONTAINING CULTURING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2017/115774
Kind Code:
A1
Abstract:
Provided is a method for stably producing carotenoid at a high yield by means of microorganism culturing. The method for culturing carotenoid-producing bacteria is characterized in that a carotenoid-producing bacteria is cultured using a culturing medium containing cobalt or a cobalt salt at a concentration of 0.005-20 μmol/L.
