To provide a method for efficiently producing an astaxanthin-containing lipid with which a method for culturing a green alga Haematococcus pluvialis is improved and a cyst is thereby formed and matured under dark conditions.
A method for producing an algal body of the green alga Haematococcus pluvialis in which astaxanthin is accumulated in an amount of ≥40-700 pg/cell in the cyst obtained by culturing the green alga Haematococcus pluvialis under conditions of 0.01-0.5 vvm relative volume of ventilation in the dark. Furthermore, there is provided the method for producing the astaxanthin-containing lipid consisting essentially of a component selected from the group consisting of free type astaxanthin, an astaxanthin fatty acid monoester, an astaxanthin fatty acid diester and a mixture thereof. The method is characterized by affording the astaxanthin-containing substance from the algal body.
