In this study, a promising microbial fuel cell (MFC) system has been developed, wherein algae is cultivated in the cathode chamber, algae biomass is harvested and lipids are extracted. The lipid extracted algal (LEA) biomass was then used asan electron donor substrate. The performance of MFCs fed with LEA biomass was compared with that of fruit waste fed MFCs (FP-MFCs), wherein LEA-fed MFC was superior in all aspects. Power density of 2.7Wm was obtained by LEA-fed MFCs which is 145% and 260% higher than FP MFC and control MFC respectively. The volumetric algae productivity of 0.028kgmday in cathode chamber was achieved. The system was able to generate 0.0136kWhKgCODday of electric energy and 0.0782kWhmday of algal oil energy. The proposed system is a net energy producer which does not rely heavily on the external supply of electron donor substrates.
在这项研究中，开发了一种有前途的微生物燃料电池（MFC）系统，其中在阴极室中培养藻类，收获藻类生物质并提取脂质。然后将提取的脂质藻类（LEA）生物质用作电子供体底物。将用 LEA 生物质喂养的 MFC 的性能与用水果废物喂养的 MFC（FP-MFC）的性能进行了比较，其中 LEA 喂养的 MFC 在各方面都具有优势。LEA 喂养的 MFC 的功率密度达到 2.7Wm，分别比 FP-MFC 和对照 MFC 高 145%和 260%。在阴极室中实现了 0.028kgmday 的藻类体积生产率。该系统能够产生 0.0136kWhKgCODday 的电能和 0.0782kWhmday 的藻类油能量。该系统是一种净能源产生器，不依赖于外部电子供体底物的供应。
