The attachment of Escherichia coli and Streptococcus bovis of bovine faecal origin to soil clay particles has been examined using scanning electron microscopy. Both organisms produce extracellular polymers through which the cells form bridges to clay surfaces. Differences in the extent of cell‐to‐particle bridging between E. coli ‐and S. bovis ‐soil complexes are explained in terms of the charge characteristics of the cells and the properties of the exopolymers.
