The benthic filamentous cyanobacteria Phormidium J‐1 and Anabaenopsis circularis 6720 adsorbed suspended clay particles and coflocculated with them. Coflocculation was correlated with production of extracellular flocculants. In old cultures there was a decrease in both coflocculating activity and cell surface hydrophobicity. It is proposed that attachment to the benthos is facilitated by the common action of both coflocculation and hydrophobic interactions. A simultaneous decrease in these two surface characteristics enables the cells to detach and colonize new surfaces.
