Abstract:
The present invention provides a method for collecting a carotenoid from a culture of a carotenoid-producing bacterium at high yield. Specifically, the present invention provides a method for separating a carotenoid comprising a step of precipitating a concentrate containing the carotenoid from a culture of a carotenoid-producing bacterium under acidic conditions; and a method for producing a carotenoid comprising the steps of precipitating a concentrate containing the carotenoid from a culture of a carotenoid-producing bacterium under acidic conditions and collecting the carotenoid from the obtained precipitate.
