Microalgae Cultivation for the Biotransformation of Birch Wood Hydrolysate and Dairy Effluent
In order to investigate environmentally sustainable sources of organic carbon and nutrients, four Nordic green microalgal strains, Chlorella sorokiniana , Chlorella saccharophila , Chlorella vulgaris, and Coelastrella sp., were grown on a wood (Silver birch, Betula pendula ) hydrolysate and dairy ef...

In order to investigate environmentally sustainable sources of organic carbon and nutrients, four Nordic green microalgal strains, Chlorella sorokiniana , Chlorella saccharophila , Chlorella vulgaris, and Coelastrella sp., were grown on a wood (Silver birch, Betula pendula ) hydrolysate and dairy effluent mixture.

Of all of the species, Coelastrella sp. produced the most total lipids per dry weight (~40%) in the mixture of birch hydrolysate and dairy effluent without requiring nutrient (nitrogen, phosphorus, and potassium—NPK) supplementation. Overall, in the absence of NPK, the two-stage mixotrophic/heterotrophic cultivation enhanced the lipid concentration, but reduced the amount of biomass. Culturing microalgae in integrated waste streams under mixotrophic growth regimes is a promising approach for sustainable biofuel production, especially in regions with large seasonal variation in daylight, like northern Sweden.
