Abstract

In this study, bioelectrochemical energy harvesting technology using a microbial fuel cell (MFC) is proposed which can generate electric energy from beverage residues containing abundant chemical energy. Various beverage residues (coffee, orange juice, soda, milk, yogurt, energy-drink, beer) were inoculated into the MFCs and results were observed. Output characteristics of the MFCs showed differences among all kind of beverages. These results showed that the activity of the microbes in the MFCs was varied due to differences in organic components of each beverage. However, MFCs successfully generated electric energy with all types of beverages used in the study. Moreover, there was a significant improvement in output performance compared with the control group which is inoculated with an initial substrate (vermicompost). MFCs inoculated with coffee and energy-drink generated a maximum power of above $50\ \mu\mathbf{W}$ which was 100 times higher than that of control MFC. It is expected that bioelectrochemical energy harvesting technology including MFC could be advanced into a sustainable power system beyond the pollutant treatment.

利用微生物燃料电池从饮料残留物中获取能量

本研究提出了一种利用微生物燃料电池(MFC)的生物电化学能量收集技术，该技术可以从含有丰富化学能的饮料残渣中产生电能。将咖啡、橙汁、苏打水、牛奶、酸奶、能量饮料、啤酒等各种饮料残留物接种到mfc中，观察结果。不同类型饮料的mfc输出特性存在差异。这些结果表明，由于每种饮料的有机成分不同，mfc中微生物的活性也有所不同。然而，在研究中使用的所有类型的饮料中，mfc都成功地产生了电能。此外，与接种初始底物(蚯蚓堆肥)的对照组相比，产量有显著提高。接种咖啡和能量饮料的MFC产生的最大功率大于$50\ \mu\mathbf{W}$，是对照MFC的100倍。包括MFC在内的生物电化学能量收集技术有望发展成为超越污染物处理的可持续电力系统。
