本研究提出了一种创新的基于微生物燃料电池的一氧化碳（CO）监测生物传感器。生物传感器功能的假设是，CO抑制阳极中的细菌活性，从而减少电力产生。将阳极上成熟的电化学活性生物膜暴露于不同浓度的CO气体。在CO浓度的10%~ 70%范围内，CO浓度与电压降（0.8 ~ 24 mV）呈线性关系（R2= 0.987）。值得注意的是，通过进一步增加CO浓度超过70%，没有观察到电压输出的进一步降低。该传感器的响应时间为1 h。紧凑的设计和简单的操作的生物传感器，使它很容易被集成在现有的CO为基础的工业设施，无论是作为一个预警传感器CO毒性，甚至作为一个单独的在线监测设备。
This study presents an innovative microbial fuel cell-based biosensor for carbon monoxide (CO) monitoring. The hypothesis for the function of the biosensor is that CO inhibits bacterial activity in the anode and thereby reduces electricity production. A mature electrochemically active biofilm on the anode was exposed to CO gas at varied concentrations. A proportional linear relationship (R2= 0.987) between CO concentration and voltage drop (0.8 to 24 mV) in the range of 10% and 70% of CO concentration was observed. Notably, no further decrease of voltage output was observed by with further increasing CO concentration over 70%. Besides, the response time of the biosensor was 1 h. The compact design and simple operation of the biosensor makes it easy to be integrated in existing CO-based industrial facilities either as a forewarning sensor for CO toxicity or even as an individual on-line monitoring device.
