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. Procédé de production d'astaxanthine comprenant : (a) la réalisation d'une culture hétérotrophe d'Haematococcus pluvialis produisant de l'astaxanthine ; (b) la réalisation d'une culture hétérotrophe de l'Haematococcus pluvialis obtenu à l'étape (a) dans des conditions de concentration élevée en acétate et de concentration élevée en oxygène dissous, la concentration en acétate étant d'au moins 1 800 mg/l et la concentration en oxygène dissous étant d'au moins 2,0 mg/l ; et (c) la collecte de cellules d'algues à partir de l'étape (b) et/ou la récolte d'astaxanthine. L'invention concerne également un milieu de base pour la culture d'Haematococcus pluvialis, un milieu d'alimentation de propagation et un milieu d'alimentation par induction.
