More Information
Summary:Provided is a method for producing astaxanthin, comprising: (a) performing heterotrophic cultivation of astaxanthin-producing Haematococcus pluvialis; (b) performing heterotrophic cultivation of the Haematococcus pluvialis obtained in step (a) under conditions of high acetate concentration and high dissolved oxygen concentration, where the acetate concentration is at least 1800 mg/L and the dissolved oxygen concentration is at least 2.0 mg/L; and (c) collecting algae cells from step (b) and/or harvesting astaxanthin. Also provided is a base medium for culturing Haematococcus pluvialis, a propagation feed medium, and an induction feed medium.
