Uses
Chlorella vulgaris, a green alga that is widely used as a food supplement, has good antioxidant and therapeutic properties.
Preparation
Under more hostile conditions, the biomass decreases, but lipids and starch contents increase.Under nutrient and light-replete conditions, protein content increases along with the biomass.Different growth techniques have been developed. Different modes of growth (autotrophic, heterotrophic, and mixotrophic) has been investigated for Chlorella vulgaris; autotrophic growth is favoured as it does not require provision of costly organic carbon and relies on inorganic carbon sources (CO2, carbonates) and light for photosynthesis.
