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 is a method for culturing photosynthetic microalgae, involving: (A) a step for increasing the number of cells by subjecting encysted photosynthetic microalgae including xanthophyll to 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. The light irradiation (a) and the light irradiation (b) are light irradiations employing different light sources, wherein: the light irradiation (a) is light irradiation that employs, as a light source, an LED including blue light having a wavelength from 400 to 490 nm; and the light irradiation (b) is light irradiation that employs, as a light source, an LED including blue light having a wavelength from 400 to 490 nm and an LED including red light having a wavelength from 620 to 690 nm.
