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.
研究了海藻希瓦氏菌BrY对水合氧化铁、针铁矿和赤铁矿的粘附情况。对每种氧化物的粘附均符合朗缪尔吸附模型。未观察到粘附与Fe(III)氧化物表面积或结晶度之间存在相关性。ζ电位测量表明，静电相互作用不影响海藻希瓦氏菌BrY对这些矿物的粘附。细胞粘附似乎无法解释结晶Fe(III)氧化物对细菌还原的抗性。
