Nodularia spumigena. Nodularia is a genus of filamentous nitrogen-fixing cyanobacteria, or blue-green algae. They occur mainly in brackish or salinic waters, such as the hypersaline Makgadikgadi Pans, the Peel-Harvey Estuary in Western Australia or the Baltic Sea. Nodularia cells occasionally form heavy algal blooms. Nodularia spumigena on tsüanobakterite rühma kuuluv ülemaailmse levikuga sinivetikaliik, mis tihti põhjustab toksilist veeõitsengut. Teadaolevatest sinivetikaliikidest Läänemerel omistatakse Nodularia spumigenale kõige ulatuslikum negatiivne mõju ümbritsevatele organismidele.
