Direct interspecies electron transfer (DIET) may be most important in methanogenic environments, but mechanistic studies of DIET to date have primarily focused on cocultures in which fumarate was the terminal electron acceptor. To better understand DIET with methanogens, the transcriptome of Geobacter metallireducens during DIET-based growth with G. sulfurreducens reducing fumarate was compared with G. metallireducens grown in coculture with diverse Methanosarcina. The transcriptome of G. metallireducens cocultured with G. sulfurreducens was significantly different from those with Methanosarcina. Furthermore, the transcriptome of G. metallireducens grown with Methanosarcina barkeri, which lacks outer-surface c-type cytochromes, differed from those of G. metallireducens cocultured with M. acetivorans or M. subterranea, which have an outer-surface c-type cytochrome that serves as an electrical connect for DIET. Differences in G. metallireducens expression patterns for genes involved in extracellular electron transfer were particularly notable. Cocultures with c-type cytochrome deletion mutant strains, ∆Gmet_0930, ∆Gmet_0557 and ∆Gmet_2896, never became established with G. sulfurreducens but adapted to grow with all three Methanosarcina. Two porin-cytochrome complexes, PccF and PccG, were important for DIET; however, PccG was more important for growth with Methanosarcina. Unlike cocultures with G. sulfurreducens and M. acetivorans, electrically conductive pili were not needed for growth with M. barkeri. Shewanella oneidensis, another electroactive microbe with abundant outer-surface c-type cytochromes, did not grow via DIET. The results demonstrate that the presence of outer-surface c-type cytochromes does not necessarily confer the capacity for DIET and emphasize the impact of the electron-accepting partner on the physiology of the electron-donating DIET partner.
种间直接电子传递（DIET）在产甲烷环境中可能最为重要，但迄今为止对 DIET 的机理研究主要集中在以富马酸盐为终端电子受体的共培养物中。为了更好地了解甲烷菌的 DIET，研究人员比较了在 DIET 基础上与还原富马酸的 G. sulfurreducens 共同生长的 Geobacter metallireducens 和与不同的 Methanosarcina 共同生长的 Geobacter metallireducens 的转录组。与 G. sulfurreducens 共培养的 G. metallireducens 的转录组明显不同于与 Methanosarcina 共培养的 G. metallireducens。此外，与缺乏外表面 c 型细胞色素的 Methanosarcina barkeri 共同培养的 G. metallireducens 的转录组与与 M. acetivorans 或 M. subterranea 共同培养的 G. metallireducens 的转录组不同，后者具有外表面 c 型细胞色素，可作为 DIET 的电连接。参与细胞外电子传递的基因在 G. metallireducens 中的表达模式差异尤其明显。与 c 型细胞色素缺失突变株 ∆Gmet_0930、∆Gmet_0557 和 ∆Gmet_2896 的共培养从未与 G. sulfurreducens 建立起来，但却适应了与所有三种 Methanosarcina 的生长。两种孔蛋白-细胞色素复合物（PccF 和 PccG）对 DIET 很重要；但 PccG 对与 Methanosarcina 的生长更为重要。与 G. sulfurreducens 和 M. acetivorans 的共培养不同，与 M. barkeri 的生长不需要导电纤毛。Shewanella oneidensis 是另一种电活性微生物，具有丰富的外表面 c 型细胞色素，但没有通过 DIET 生长。这些结果表明，外表面 c 型细胞色素的存在并不一定赋予 DIET 的能力，并强调了接受电子的伙伴对提供电子的 DIET 伙伴的生理机能的影响。
