The tube-shaped yellow-green alga Vaucheria velutina (Xanthophyceae, Stramenopiles) has been elected as "Alga of the year 2021" by the German Botanical Society. It supports the cooperation of mudflat researcher Prof. em. Dr. Karsten Reise of the Alfred-Wegener-Institute for Polar and Marine Sciences (AWI) and Dr. Nataliya Rybalka, who is performing research on yellow-green algae (Xanthophyceae) using molecular methods at the Sammlung von Algenkulturen der Universität Göttingen (SAG), department EPSAG. At present, the SAG provides four culture strains of Vaucheria to the public.
