微生物毛发可以导电

根据美国南加州大学的生物物理学家们的研究, 有些细胞培养的电子毛发可以连接成很大的生物电流。这一发现意味着微生物群落可以部分通过导电的毛发, 又称为细菌纳米线, 得以生存、交流和分享能量。

“这是对由细菌生成的纳米线电流传输的首次测量。” USC大学文理学院物理與天文副教授Mohamed El-Naggar先生表示。El-Naggar是下周出版的《美国国家科学院院刊》一片论文的主要作者。

了解微生物群落是如何发展的是找到消灭有害群落,如生物膜,方法的第一步。生物膜对抗生素有很强的抗体。

同样的知识,也有助于促进有益群落,比如USC和其他机构正在研究的细菌燃料电池中的有益群落。“不同方向流动的电流与生物膜不同部分的代谢状态有密切关系。” El-Naggar先生表示,“细菌纳米线可以为微生物电流的存活提供这样的连接。”
