利用微生物作为碳源，开发了一种利用生物柴油生产过程中产生的副产物甘油发电的微生物燃料电池(MFC)系统。从土壤和滨水环境中分离出以甘油为唯一碳源的微生物。最后，获得了5株能够在含有10%甘油的培养基中生长的微生物，并在我们的MFC系统中进行了甘油发电试验。五种微生物中有三种显示了发电能力。其中，菌株1在2-羟基-1，4-萘酚存在下的最大输出功率为0.102 mW/cm2。当使用甘油作为底物时，菌株1的最大功率值高于葡萄糖，这表明介体向电极的电子转移是MFC性能的限速步骤，而不是底物的降解。
A microbial fuel cell (MFC) system to generate electric power from glycerol, a by-product generated in the production process of biodiesel, was developed using microbes utilizing glycerol as a carbon source. Microorganisms utilizing glycerol as a sole carbon source were isolated from the soil and waterfront environments. Finally, five microbes which were able to grow up in the medium containing 10% glycerol were obtained and examined to generate electric power from glycerol in our MFC system. Three of the five microbes showed electric power generation. Especially, Isolate 1 showed the greatest values of maximum power output, 0.102 mW/cm 2, in the presence of 2-hydroxy-1, 4-naphoquinone as a mediator. Isolate 1 showed higher maximum power value when using glycerin as a substrate than glucose, suggesting that electron transfer to the electrode by the mediator is a rate limiting step of MFC performance rather than substrate degradation.
