摘要：

Shewanella alga BrY adhesion to hydrous ferric oxide, goethite, and hematite was examined. Adhesion to each oxide followed the Langmuir adsorption model. No correlation between adhesion and Fe(III) oxide surface area or crystallinity was observed. Zeta potential measurements suggested that electrostatic interactions do not influence S. alga BrY adhesion to these minerals. Cell adhesion does not appear to explain the recalcitrance of crystalline Fe(III) oxides to bacterial reduction.
