Graphene materials (GMs) are being investigated for multiple microbiological applications because of their unique physicochemical characteristics including high electrical conductivity, large specific surface area, and robust mechanical strength. In the last decade, studies on the interaction of GMs with bacterial cells appear conflicting. On one side, GMs have been developed to promote the proliferation of electroactive bacteria on the surface of electrodes in bioelectrochemical systems or to accelerate interspecies electron transfer during anaerobic digestion. On the other side, GMs with antibacterial properties have been synthesized to prevent biofilm formation on membranes for water treatment, on medical equipment, and on tissue engineering scaffolds. In this review, we discuss the mechanisms and factors determining the positive or negative impact of GMs on bacteria. Furthermore, we examine the bacterial growth-promoting and antibacterial applications of GMs and debate their practicability.
由于石墨烯材料（GMs）具有独特的物理化学特性，包括高导电性、大比表面积和强大的机械强度，因此正在对其进行多种微生物学应用的研究。在过去十年中，关于GMs与细菌细胞相互作用的研究似乎相互矛盾。一方面，GMs已被开发用于促进生物电化学系统中电极表面电活性细菌的增殖，或在厌氧消化过程中加速种间电子转移。另一方面，具有抗菌特性的GMs已被合成，以防止在水处理膜、医疗设备和组织工程支架上形成生物膜。在这篇综述中，我们讨论了决定GMs对细菌产生正面或负面影响的机制和因素。此外，我们研究了GMs促进细菌生长和抗菌的应用，并对其实用性进行了辩论。
