近十年来，随着微生物燃料电池的发展和微生物纳米线的发现，电微生物学发展势头迅猛。产生MNWs的微生物的名单正在增长，并提供了有趣的见解，了解这些微生物在不同环境中的存在以及MNWs可以发挥的潜在作用。本文综述了由不同微生物产生的微颗粒，包括它们的结构、组成及其在微颗粒电子传递中的作用。两个假设，金属样电导率和电子跳跃模型，已经提出了电子转移，我们目前的理解这两个假设。MNWs不仅有望改变我们看待微生物的方式，而且可能影响生物能源、生物地球化学和生物修复领域，因此它们在这些领域的潜在应用在这里强调。
Electromicrobiology has gained momentum in the last ten years with advances in microbial fuel cells and the discovery of microbial nanowires (MNWs). The list of MNWs producing microorganisms is growing and providing intriguing insights into the presence of such microorganisms in diverse environments and the potential roles MNWs can perform. This review discusses the MNWs produced by different microorganisms, including their structure, composition and role in electron transfer through MNWs. Two hypotheses, metallic-like conductivity and an electron hopping model, have been proposed for electron transfer and we present a current understanding of both these hypotheses. MNWs are not only poised to change the way we see microorganisms but may also impact the fields of bioenergy, biogeochemistry and bioremediation, hence their potential applications in these fields are highlighted here.
