硫还原地杆菌是一种三角洲变形菌，它的全基因组序列揭示了意想不到的能力，包括有氧代谢、单碳和复杂碳代谢、运动性和趋化行为的证据。这些特性，再加上许多双组分传感器和许多c型细胞色素，揭示了创建替代的、冗余的电子传递网络的能力，并为地下环境中金属离子还原的过程提供了见解。除了在金属和碳的全球循环中发挥作用外，这种生物显然具有用于放射性金属的生物修复和发电的潜力。
The complete genome sequence of Geobacter sulfurreducens, a delta-proteobacterium, reveals unsuspected capabilities, including evidence of aerobic metabolism, one-carbon and complex carbon metabolism, motility, and chemotactic behavior. These characteristics, coupled with the possession of many two-component sensors and many c-type cytochromes, reveal an ability to create alternative, redundant, electron transport networks and offer insights into the process of metal ion reduction in subsurface environments. As well as playing roles in the global cycling of metals and carbon, this organism clearly has the potential for use in bioremediation of radioactive metals and in the generation of electricity.
