Abstract
The present invention provides a method for high yield and stable production of carotenoids through microbial culture. The present invention provides a method for culture of carotenoid-producing bacteria, which comprises culturing carotenoid-producing bacteria in a medium containing cobalt or a cobalt salt at a concentration of 0.005 μmol/L to 20 μmol/L.
Claims18
A method for stable preparation of microbial cells containing carotenoids in an amount of at least 36 mg/g in dry microbial cells, comprising culturing bacteria belonging to the genus Paracoccus in a medium containing cobalt or a cobalt salt at a concentration of 0.005 μmol/L to 7 μmol/L, wherein the culturing step is carried out by aeration spinner culture.
A method for production of carotenoids, comprising culturing bacteria belonging to the genus Paracoccus in a medium containing cobalt or a cobalt salt at a concentration of 0.005 μmol/L to 7 μmol/L to thereby obtain microbial cells containing carotenoids in an amount of at least 36 mg/g in dry microbial cells, and collecting the carotenoids from the cultured product containing the microbial cells, wherein the culturing step is carried out by aeration spinner culture.
A method for stabilization of carotenoid levels in microbial cells such that carotenoids are contained in an amount of at least 36 mg/g in dry microbial cells, comprising culturing bacteria belonging to the genus Paracoccus in a medium containing cobalt or a cobalt salt at a concentration of 0.005 μmol/L to 7 μmol/L, wherein the culturing step is carried out by aeration spinner culture.
