Title: METHOD FOR CULTURING PHOTOSYNTHETIC MICROALGAE
Abstract:
The present invention provides a method for culturing photosynthetic microalgae, with which it is possible to obtain xanthophyll more efficiently compared to conventional art. This culturing method comprises a step for subjecting, to light irradiation, encysted photosynthetic microalgae including 3-9 mass% of xanthophyll in terms of dry mass, wherein, in the step for performing said light irradiation, it is preferable to keep the content of xanthophyll in the photosynthetic microalgae to 2 mass% or higher in terms of dry mass. The step for performing said light irradiation preferably involves: (A) a step for increasing the number of cells by performing light irradiation (a); and (B) a step for increasing the content of xanthophyll in the photosynthetic microalgae by subjecting, to light irradiation (b), the photosynthetic microalgae that has undergone the step (A) for increasing the number of cells.
