Title:

A production method of astaxanthin

Document Type and Number:

Japanese Patent JP6158427

Kind Code:

B2

Abstract:

A method for increasing efficiency of a method for producing astaxanthin by culturing a microalga. A method for producing astaxanthin in which astaxanthin is produced in an algal body by culturing a microalga, wherein photoirradiation is performed using both a blue LED of peak wavelength from 420 to 500 nm and a red LED of peak wavelength from 620 to 690 nm, at least during an astaxanthin-producing culturing phase of a culturing period. The ratio of the blue LED of peak wavelength from 420 to 500 nm and the red LED of peak wavelength from 620 to 690 nm is preferably from 1:19 to 19:1 by photon flux density, and the photon flux densities are each preferably not less than 20 μmol/m2/s.
