The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



a mucilaginous formation that arises with the cohesion of bacteria that secrete mucus or have mucous capsules. Zoogloea consists of polysaccharides, sometimes with an admixture of nitrogenous compounds. It is characteristic only of certain bacteria (predominantly aquatic ones), particularly the genus Zoogloea ramigera (hence the name). A zoogloea’s possible forms include digitate, coralloidal, and mesenteric. The origin of zoogloea is apparently adaptive: its mucoid consistency permits it to readily adsorb nutritive substances necessary for its existence from water.
