Doctoral project: Mixotrophic cultivation of microalgae for nutrient and CO2 recovery from waste streams

Microalgae can efficiently recover nutrient and CO2 from industrial waste streams. Mixotrophic cultivation mode of microalgae, which is more productive than the common autotrophic mode, is investigated in autumns and winters in this study.

More about the project

Microalgal solutions for bioremediation of waste provide a new efficient way of recovering nutrients and carbon dioxide (CO2) from industrial waste streams, with the additional benefit of producing valuable biomass. This project aims to improve performance of algal solutions using mixotrophic microalgae that can utilize an organic carbon source and simultaneously photosynthesize. Mixotroph production will extend the cultivation season during winter conditions of low temperature and light, as well as increasing the recovery efficiency on a yearly basis.

The project is part of the research in the research group Marine phytoplankton ecology and applications (MPEA) and in Linnaeus University Centre for Ecology and Evolution in Microbial model Systems (EEMiS).
