During the last decade, bioprospecting for electrochemically active bacteria has included the search for new sources of inoculum for microbial fuel cells (MFCs). However, concerning power and current production, a Geobacter-dominated mixed microbial community derived from a wastewater inoculum remains the standard. On the other hand, cathode performance is still one of the main limitations for MFCs, and the enrichment of a beneficial cathodic biofilm emerges as an alternative to increase its performance. Glucose-fed air-cathode reactors inoculated with a rumen-fluid enrichment and wastewater showed higher power densities and soluble chemical oxygen demand (sCOD) removal (Pmax = 824.5 mWm−2; ΔsCOD = 96.1%) than reactors inoculated only with wastewater (Pmax = 634.1 mWm−2; ΔsCOD = 91.7%). Identical anode but different cathode potentials suggest that differences in performance were due to the cathode. Pyrosequencing analysis showed no significant differences between the anodic community structures derived from both inocula but increased relative abundances of Azoarcus and Victivallis species in the cathodic rumen enrichment. Results suggest that this rarely used inoculum for single-chamber MFCs contributed to cathodic biofilm improvements with no anodic biofilm effects.

Compost Solid Phase Microbial Fuel Cells (CSMFCs) merupakan teknologi pengomposan yang diintegrasikan dengan sistem MFCs untuk menghasilkan kompos dan produksi biolistrik dari sampah padat organik. Penelitian ini bertujuan untuk meningkatkan kinerja CSMFCs melalui penerapan perlakuan optimal dari penelitian terdahulu seperti, kadar air 60%, volume sampah 2/3 reaktor, dan penambahan bioaktivator. CSMFCs dalam penelitian ini dilakukan dalam kondisi batch menggunakan reaktor tipe single chamber dan dual anode graphene. Sampah daun dan sampah sisa makanan digunakan sebagai substrat dalam studi ini. Bahan sampah tersebut divariasikan berdasarkan rasio bahan (sampah daun:sampah sisa makanan) yaitu 100:0, 0:100, dan 50:50. Hasil penelitian ini menunjukan kinerja CSMFCs yang optimum terdapat pada variasi sampah campuran keduanya dengan rasio bahan 50:50. Variasi ini dapat menghasilkan kompos yang baik, yaitu memenuhi SNI 19-7030-2004, serta produksi listrik yang cukup tinggi yaitu power density 41,6 mW/m2, coulombic efficiency 0,647% dan energy efficiency 0,0127%.
