Following an investigation of the influence on flocculation of conditions in the medium and of treatments directly affecting the cell surface, it is concluded that a tendency to rapid flocculation can be explained on the basis of the existence of ionogenic groups in the cell surface; anionic groups predominate and are apparently provided by nucleic adds and by carboxyl groups, whilst kationic groups are provided by a glucosamine polymer. Accessibility of the kationic groups is the factor governing flocculation and can be affected by conditions in the medium.
