The hydrophobicities and electrophoretic mobilities of isolates from methanogenic anaerobic granular sludge were measured and compared with those of strains from culture collections. All new isolates were highly hydrophobic, indicating that the upflow anaerobic sludge blanket reactor concept selects for hydrophobic bacteria. Methanothrix soehngenii, a methanogen often observed in methanogenic granular sludge, was highly hydrophobic and showed low electrophoretic mobility at pH 7. The role of this strain in the formation of methanogenic granular sludge is discussed.
测定了产甲烷厌氧颗粒污泥分离物的疏水性和电泳迁移率，并与从培养物中分离的菌株进行了比较。所有新分离物均具有高疏水性，表明上流式厌氧污泥床反应器概念选择了疏水性细菌。在产甲烷颗粒污泥中经常观察到的产甲烷菌 Methanothrix soehngenii 具有高疏水性，在 pH 值为 7 时电泳迁移率较低。讨论了该菌株在产甲烷颗粒污泥形成中的作用。
