硫还原地杆菌 PCA 完全氧化乳酸并还原铁或电极，产生丙酮酸和乙酸中间体。与 Shewanella oneidensis MR-1 产生的电流相比，G.sulfurreducens PCA 在乳酸喂养的微生物电解池中产生的电流水平高出 10 倍。本文报道的动力学和比较分析表明，硫还原杆菌菌株在提供乳酸的金属和电极还原群落中发挥着重要作用。
Geobacter sulfurreducens PCA completely oxidized lactate and reduced iron or an electrode, producing pyruvate and acetate intermediates. Compared to the current produced by Shewanella oneidensis MR-1, G. sulfurreducens PCA produced 10-times-higher current levels in lactate-fed microbial electrolysis cells. The kinetic and comparative analyses reported here suggest a prominent role of G. sulfurreducens strains in metal- and electrode-reducing communities supplied with lactate.
