Abstract Several floc-forming bacteria were isolated from polluted water by this and other laboratories. All organisms studied produced extracellular polymer fibrils that were related to slime matrix and flocculation. The extracellular polymers have high adsorption capacity for: soluble metal and other mineral ions, soluble organic nutrients (BOD), soluble toxic organics, insoluble mineral particles and insoluble organic particulates. The bacteria remove BOD by physical adsorption as well as by oxidative metabolism and can convert oxygen demanding organics to more extracellular polymer. Production of polymer can be stimulated nutritionally to yield amounts that have waste treatment-pollution abatement potential on a commercial scale. The relationship of bioflocculation to waste treatment and lake eutrophication is discussed and the basic mechanism of bioflocculation is considered. Biochemical activities of individual floc-forming cells is examined because of its relevance to polymer synthesis. Taxonomy of floc-formers is also considered in relationship to biochemical activities.
