4P00060-14 Autotrophic and heterotrophic algae cultivation in industrial waste streams: characterization of the biomass quality

The aim of the project is to produce high quality algal biomass from industrial waste streams such as pulp and paper and dairy. The total protein, lipid and carbohydrate
contents will be measured and amino acid and lipid profiles evaluated. This
qualitative characterization will give pivotal information about which animal
would be most suitable recipient for the algae biomass feed. Another goal with
the project is to evaluate the best harvesting method for the algae by using
the pilot equipment at SP Processum.

In this project, alga was investigated if it could grow on local industrial waste streams. Both autotrophic algae (using sunlight as energy source) and heterotrophic algae (using organic carbon as energy source) was allowed to grow on residual streams from the pulp- and paper industry and the dairy industry. Of the three algae used in autotrophic growth, two showed a fatty acid profile that was excellent for biodiesel production and the third alga had an elevated level of the unusual amino acid cysteine. The heterotrophic algae grew best when the growth media contained residual streams from both the pulp- and paper industry and dairy industry.
