Summary

The pure culture flocculation of Flavobacterium sp. strain 304 was shown to be limited to early stationary phase cells. The effects of proteolytic, cellulolytic and nucleolytic enzymes as well a agents such as divalent ions, citrate, malate, EDTA, poly-l-lysine, and NaN3 on flocculation was studied. The results indicate that the flocculation of strain 304 is protein mediated, and affected by composition of the growth medium. The primary interaction between the cells is not ionic or divalent cation dependent, but probably hydrophobic in nature. In addition, the role of single-species flocculation in activated sludge is discussed.
