In order to study the synergistic effects between Azolla and Anabaena in the removal of uranium from wastewater by Azolla–anabaena symbiotic system (AASS), the Azolla without Anabaena (AWA) was separated from the AASS. The removal of uranium by the AWA and the AASS, the growth inhibition, the solution protein contents, the superoxide dismutase, catalase and peroxidase activities under the stress of different uranium solutions were measured and analyzed. The results show that there were synergistic effects between Azolla a...
