Abstract
The present invention relates to the field of culturing unicellular red algae (URA). The invention relates in particular to a method for culturing URA, characterised in that the culture medium includes milk permeate as the main contribution of at least one carbon source. The invention also relates to biomass which can be obtained by the method according to the invention, to the uses of said biomass and to the products that can include said biomass.
Claims14
A method for producing unicellular red algae (URA) biomass, said URA being selected from the genus Galdieria, the method comprising the following steps:
- a) culturing said unicellular red algae (URA) in a medium containing at least one lacteal permeate selected from milk permeate, whey permeate, buttermilk and mixtures thereof;
- said lacteal permeate comprising lactose as carbon source and organic acids selected from lactic acid and citric acid;
- and
- b) collecting from the culture medium the biomass produced containing said URA,
- wherein the lactose from lacteal permeate is at an initial concentration in the culture medium ranging between 0.05 g/L and 200 g/L;
- and
- wherein the biomass produced has a URA density of between 20 and 200 g/L dry matter.
