Abstract

Microbial fuel cell (MFC) is a developed technology to utilize microbial degradation ability and turned the degradation products to electricity. One of the limiting factor that contributes to the performance level of MFC is the microorganism used in the MFC. In the present research, Bacilli E1 has been tested for its ability to utilize glucose and converted it to electricity in dual chamber MFC. The MFC operated using E1 produced a maximum average of open circuit voltage (OCV) of 0.8 V.  Meanwhile, by inserting a 1000 Ω resistance in the MFC circuit, produced a stable voltage of 0.1 V and calculated current and power were 0.2 ± 0.017 mA and 0.1 Wm^-2 Comparison of glucose based voltage production between individual and mixed culture shows similar pattern of voltage profile and since individual CC did not show any significant increase of OCV, it was concluded that Bacilli E1 plays major role in the present MFC for power production.

Abstrak

Sel bahan api berasaskan mikrob (MFC) adalah satu teknologi terbangun yang menggunakan keupayaan mikroorganisma mendegradasi dan menukarkan produk degradasi kepada elektrik. Antara yang menjadi faktor penghad yang menyumbangkan kepada tingkat prestasi MFC adalah mikroorganisma yang digunakan di dalam MFC. Dalam kajian ini, Bacilli E1 telah diuji keupayaannya untuk menggunakan glukosa dan menukarkannya kepada elektrik dalam dwikebuk MFC. MFC yang dijalankan dengan menggunakan E1, telah menghasilkan voltan litar terbuka (OCV) sebanyak 0.8 V. Manakala, dengan memasukkan rintangan sebanyak 1000 Ohm dalam litar MFC menghasilkan voltan yang stabil berjumlah 0.1 V serta jumlah arus dan kuasa yang dikira adalah masing-masing 0.2 ± 0.017 mA dan 0.1 Wm^-2. Perbandingan antara penghasilan voltan daripada glukosa menggunakan individu dan kultur campuran adalah hampir serupa dan memandangkan CC secara individu tidak menunjukkan sebarang kenaikan dalam OCV, maka kesimpulan dibuat bahawa Bacilli E1 memainkan peranan besar dalam MFC yang dijalankan untuk penghasilan kuasa..
