Title:
METHOD FOR PROMOTING GROWTH OF GREEN ALGAE
Document Type and Number:
WIPO Patent Application WO/2014/119792
Kind Code:
A1
Abstract:
A method for growing green algae, in which green algae that store astaxanthin are irradiated with artificial light so as to promote the growth of the green algae in a green motile cell state, is characterised by irradiating the green algae intermittently with blue illumination light while irradiating the green algae continuously with red illumination light, and by growing the green algae in a liquid culture medium while maintaining the culture solution of the green algae in a green or brown state.
