  • Patent number: 11606912
    Abstract: An object of the present invention is to provide a method that can effectively/efficiently increase the amount of a phenolic compound such as a polyphenol. The invention provides a method for increasing an amount of a phenolic compound in a plant, or a method for producing a plant containing an increased amount of a phenolic compound, the method comprising irradiating the/a plant with ultraviolet light, wherein a fluence at wavelengths of 270 to 290 nm is 1500 to 50000 ?mol/m2 and a fluence at wavelengths of 310 to 400 nm is less than 50% of that at wavelengths of 270 to 290 nm.

  • Publication number: 20230002721
    Abstract: A method of cultivating algal cells of an algae belonging to a class selected from Chlorophyceae, Euglenophyceae, Bacillariophyceae and Haptophyceae includes: irradiating the algal cells with an artificial light having a ratio of (i) photon flux density in a wavelength range of 520-630 nm to (ii) photosynthetic photon flux density, that is 65% or more; and measuring a cell size of the algal cells. Irradiation and non-irradiation of the algal cells with the artificial light are switched, or the photon flux density in the wavelength range of 520-630 nm is changed, according to the measured cell size.

  • Patent number: 11473051
    Abstract: A method of cultivating algal cells of an algae belonging to a class selected from Chlorophyceae, Euglenophyceae, Bacillariophyceae and Haptophyceae includes: irradiating the algal cells with an artificial light having a ratio of (i) photon flux density in a wavelength range of 520-630 nm to (ii) photosynthetic photon flux density, that is 65% or more; and measuring a condition of the algal cells and/or a condition of an algal cell culture provided by cultivating the algal cells. Irradiation and non-irradiation of the algal cells with the artificial light are switched, or the photon flux density in the wavelength range of 520-630 nm is changed, according to the measured condition of the algal cells and/or the measured condition of the algal cell culture.
