Abstract

A method of culturing Haematococcus species for manufacturing of astaxanthin comprising the steps of: providing a substrate, arranging the Haematococcus species on the surface of the substrate, exposing the Haematococcus species arranged on the substrate to high light intensities from the beginning of a culturing process and avoiding a two-step culturing process of the Haematococcus species with a first step which is an initial culturing taking place by exposure of the Haematococcus species to low light energy followed by a second step of subsequent culturing of the Haematococcus species by exposure of the Haematococcus species to higher light energy than applied in the first step to induce astaxanthin formation, and optionally—harvesting the cultured Haematococcus species and/or—isolating astaxanthin.
