Microalgae Chlorella sorokiniana and duckweed Lemna minor will be cultivated in open ponds as well as closed systems in Germany and Russia. To enhance a profitability optimal cultivation and separation conditions for identified aquatic biomass will also be a priority of this project. Subsequently, a cost-efficient method for the extraction of value-added products such as proteins, carotenoids and pectin has to be developed for the food and feed industry. A part of residual biomass will further be used as sorbents for the industrial wastewater treatment from the heavy metals. At the same time, after the extraction the rest of microalgae and duckweed can be also used as substrate for anaerobic digestion with an aim to supply the whole process with the heat and electricity. CO2 which is formed during the fermentation process and after the combustion in the CHP unit will be used within the cultivation process as a carbon source for the photoautotrophic synthesis of biomass.
In order to reach this goal cooperation between German and Russian research groups will be established. The project tends to take an advantage of the state-of-the-art industrial experience and at the same time innovative research and development in both countries.
