 Optimising the proportion of pure and mixed culture in inoculum to enhance the performance of microbial fuel cellsDipak A. Jadhav and Makarand M. Ghangrekar International Journal of Environmental Technology and Management, 2020, vol. 23, issue 1, 50-67 Abstract: Single-chambered microbial fuel cells (MFCs) were inoculated with different proportions of Shewanella putrefaciens and mixed-anaerobic sludge, viz. 100:0% (MFC-1), 0:100% (MFC-2), 10:90% (MFC-3), 30:70% (MFC-4) and 50:50% (MFC-5). Performance of these MFCs was evaluated using different electrochemical analyses. Due to specific substrate-selectivity, MFC-1 showed lower power (1.22 W.m−3) than MFC-2 (2.15 W.m−3). Power performance increased from 2.21 (MFC-3) to 2.56 W.m−3 (MFC-4) with increased fraction of Shewanella from 10 to 30% in the inoculum, and power density further enhanced to 3.1 W.m−3 in MFC-5 inoculated with equal-fraction of Shewanella and mixed sludge. Bioelectrochemical analyses showed higher electron transfer rate and lower charge-transfer resistance in MFC-5 due to synergy between both the inoculums and promoted the electron transfer at anode. Thus, inoculation of MFC with equal-fraction of mixed-anaerobic sludge and Shewanella showed effective bio-augmentation to improve the anodic bioactivity and power generation from MFC.
