Abstract: The present invention relates to a heterotrophic methods of culturing algae, particularly Galdieria species, to produce the valuable pigment phycocyanin. The methods rely on high oxygen saturation and controlled base dosing to provide improved phycocyanin production. The present invention further relates to algal biomass, compositions comprising said biomass or phycocyanin, uses thereof in various products, and a reactor for culturing the algae.
