氧化亚铁杆菌外膜部分脂多糖的丧失对细菌在矿物上的附着和生物浸出过程产生了负面影响。以前从氧化亚铁硫杆菌中提取的与黄铁矿接触的脂多糖抑制了细胞与矿物的附着，也对生物浸出产生了负面影响。这些结果表明，内毒素在微生物的附着中起着重要的作用，因此，它的存在或不存在可能影响生物浸出过程。
The loss of part of the lipopolysaccharides (LPS) of the outer membrane of T, ferrooxidans negatively influenced the attachment of the bacteria to minerals and the bioleaching process. LPS previously extracted from T. ferrooxidans and which had come into contact with pyrite inhibited the attachment of cells to minerals and also negatively affected the bioleaching. These results suggest that LPS play an important role in the attachment of the microorganisms and therefore, its presence or absence could affect the bioleaching process.
