摘要

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 μW 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.
