New publication: Testing for terrestrial and freshwater microalgae productivity under elevated CO2 conditions and nutrient limitation
Microalgae CO2 fixation results in the production of biomass rich in high-valuable products, such as fatty acids and carotenoids. A large variety of 81 defined algal strains, including new green algal isolates from various terrestrial environments, were studied for their growth under atmospheres with CO2 levels of 5–25% in air. Green algae originating from terrestrial environments, Chlorophyceae and Trebouxiophyceae, exhibited enhanced productivity of carotenoids and fatty acids under elevated CO2 concentrations. This ability supports the economic and sustainable production of valuable compounds from these microalgae using inexpensive sources of high CO2 concentrations, such as industrial exhaust fumes. The tests of four new strains under 15% CO2 aeration revealed an even further increase of carotenoid and fatty acid contents when combined with nitrogen starvation.

Press release: Algae reveal clues about climate changes over millions of years
Göttingen University scientists identify and investigate algae which register sea water temperatures of the warmest months.
