It is characteristic of stationary-phase or late experimental-phase cells of some strains of yeast (Mill, 1964). Flocs are helpful in increasing the decomposition rate and are put in the aeration tank while the secondary sewage treatment process is in effect. This results in the sewage BOD(Biochemical Oxygen Demand)reducing by up to approximately 15 percent before being passed on to the settlement tanks. Aluminum sulfate (alum) is the most common coagulant used for water purification. However, work on the activated sludge bacterium Zoogloea resiniphila has shown that PEP-CTERM proteins must be expressed for flocs to form; in their absence, growth is planktonic, even though exopolysaccharide is produced.
