Geophysics是最有效的电流产生细菌物种之一，但它们的电子转移机制几乎没有在分子水平上研究。在这里，我们提供的证据表明，Gesterion细胞分泌和利用核黄素作为外膜C型细胞色素的结合辅因子。这一发现突出了核黄素作为电流生产中主要电子载体的潜在作用。
Geobacter species are among the most efficient current-producing bacterial species, yet their electron-transfer mechanisms have been scarcely investigated at the molecular level. Here, we provide evidence that Geobacter cells secrete and utilize riboflavin as a bound-cofactor in outer-membrane c-type cytochromes. This finding highlights the potential roles of riboflavin as a major electron carrier in current production.
