In this paper, we reported a kind of exoelectrogens, Pseudomonas alcaliphila (P. alcaliphila) strain MBR, which could excrete phenazine-1-carboxylic acid (PCA) to transfer electron under alkaline condition in microbial fuel cells (MFCs). The electrochemical activity of strain MBR and the extracellular electron transfer mechanism in MFCs were evaluated by cyclic voltammetry (CV) and electricity generation curve measurement. The results indicated a soluble mediator was the key factor for extracellular electron transfer of strain MBR under alkaline condition. The soluble mediator was PCA detected by gas chromatography-mass (GC-MS) analyses.
本文报道了一种能够在微生物燃料电池（MFCs）中于碱性条件下通过分泌吩嗪-1-羧酸（PCA）来传递电子的产电菌，即嗜碱假单胞菌（P. alcaliphila）MBR 菌株。通过循环伏安法（CV）和发电曲线测量来评估 MBR 菌株的电化学活性和 MFCs 中的细胞外电子传递机制。结果表明，在碱性条件下，可溶性介体是 MBR 菌株进行细胞外电子传递的关键因素。通过气相色谱-质谱（GC-MS）分析检测到该可溶性介体为 PCA。
