Flocculation by Zoogloea MP6 was accompanied by the production of a mucopolysaccharide exopolymer. Polymer formation was initiated in mid-logarithmic growth phase, and the quantity produced appeared to be influenced by the level of carbon and nitrogen in the culture medium.
Exocellular polymer was isolated from zoogloeae of Zoogloea strains MP6 and 106 and from activated sludge flocs by blending samples with phosphate buffer and precipitation of solubilized polymer with cetyltrimethylammonium bromide. Samples of polymer from these sources were similar and yielded amino sugars as the principal components after acid hydrolysis.
