Leaching bacteria such as Thiobacillus ferrooxidans attach to pyrite or sulfur by means of extracellular polymeric substances (EPS) (lipopolysaccharides). The primary attachment to pyrite at pH 2 is mediated by exopolymer-complexed iron(III) ions in an electrochemical interaction with the negatively charged pyrite surface. EPS from sulfur cells possess increased hydrophobic properties and do not attach to pyrite, indicating adaptability to the substrate or substratum.
诸如氧化亚铁硫杆菌之类的浸矿细菌通过细胞外聚合物（EPS）（脂多糖）附着在黄铁矿或硫上。在pH值为2时，与带负电荷的黄铁矿表面发生电化学相互作用，由胞外聚合物络合的铁（III）离子介导对黄铁矿的主要附着。来自硫细胞的EPS具有增强的疏水性，不会附着在黄铁矿上，这表明其对底物或基质具有适应性。
