Cable bacteria are a unique type of filamentous microorganism that can grow up to centimetres long and are capable of long-distance electron transport over their entire lengths. Due to their unique metabolism and conductive capacities, the study of cable bacteria has required technical innovations, both in adapting existing techniques and developing entirely new ones. This review discusses the existing methods used to study eight distinct aspects of cable bacteria research, including the challenges of culturing them in laboratory conditions, performing physical and biochemical extractions, and analysing the conductive mechanism. As cable bacteria research requires an interdisciplinary approach, methods from a range of fields are discussed, such as biogeochemistry, genomics, materials science, and electrochemistry. A critical analysis of the current state of each approach is presented, highlighting the advantages and drawbacks of both commonly used and emerging methods.
电缆细菌是一种独特的丝状微生物，其长度可达数厘米，能够在整个长度上进行长距离电子传输。由于其独特的代谢和导电能力，对电缆细菌的研究需要技术创新，包括对现有技术的改进和全新技术的开发。本综述讨论了用于研究电缆细菌的八个不同方面的现有方法，包括在实验室条件下培养它们的挑战、进行物理和生化提取以及分析导电机制。由于电缆细菌研究需要跨学科方法，因此讨论了一系列领域的方法，如生物地球化学、基因组学、材料科学和电化学。对每种方法的当前状态进行了批判性分析，突出了常用方法和新兴方法的优缺点。
