Nostoc

Nostoc A genus of filamentous cyanobacteria (section IV), in which the filaments have a distinctly beaded appearance under the microscope. The filaments typically aggregate to form gelatinous colonies. They are capable of nitrogen fixation. They are found in aquatic and terrestrial habitats. Nostoc punctiliforme occurs in symbiotic association with the plant Gunnera, living in the leaf bases where it fixes atmospheric nitrogen. Nostoc is also found in coralloid root nodules in cycads, as the phycobiont in certain lichens (e.g. the dog lichen, Peltigera canina), and in lichen cephalodia. Some species of Nostoc are used as food in China and Japan.

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates.

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content.
