description The ability of aquatic microalgae to treat the liquid digestate obtained from the anaerobic digestion of plant waste was investigated. Microalgae were isolated from natural environment for a laboratory-scale cultivation and were then used to remove nutrients and organic contaminants from the liquid digestate. It was shown that the microalgae consortia (<i>Tetradesmus obliquus</i>, <i>Microglena</i> sp., <i>Desmodesmus subspicatus</i>) could reduce nitrogen, phosphates, and total COD by up to 70%, 57%, and 95%, respectively. A new algae genus <i>Microglena</i> was isolated, which in a consortium with <i>Tetradesmus obliquus</i> and <i>Desmodesmus subspicatus</i> exhibited a high efficiency in the removal of both organic contaminants and nutrients from the liquid fraction of digestate.
