Abstract

Due to high energy demand worldwide, finding an alternative renewable and sustainable energy source is of great interest. Plant microbial fuel cell (P-MFC) is one of the most promising methods to generate green energy. In P-MFC, a plant is placed into the anode compartment. Mutual interaction between plant root rhizodeposits and bacterial community results in the biofilm formation at the vicinity of the rhizosphere area in plant root could be utilized to generate electricity. Indeed, in PMFC, bacteria metabolize rhizodeposits into electrons and protons. These electrons could be then converted into green electricity. The objectives of this research are to utilize Epipremnum aureum plant collected from Kota Tinggi’s lake to generate electricity and observe current generation by different resistors, to characterize immobilized bacteria attached on the anode surface then identify the optimum growth temperature for isolated bacteria. Five plant microbial fuel cells were constructed in a H-shape (dual- chambers) configuration in the plastic container. Maximum current density for 20 days for P-MFC by external resistance of 100k ? was 0.1 µA/cm2 with maximum power density of 0.85 µW/cm2 and the open circuit voltage (OCV) was measured at 195 mV. Besides, fresh biomass averages increased 5g after 20 days of experiments below and above ground as compared to the initial fresh biomass. Five isolated bacterial strains from the graphite felt surface found on the anode were screened by nine biochemical tests such as catalase, TSI (triple sugar iron agar), gelatin and etc. The immobilized bacteria attached to anode electrode in P-MFC were further examined with Fast Electron Scanning Electron Microscopy (FESEM). The isolated bacterial growth curves were determined at two different temperatures of 25 °C and 37 °C. The optimum growth temperature predominantly for them was 37 °C.
