“…is added [63]. Pure cultures capable of producing current in a MFC include representatives of the Firmicutes [64] and Acidobacteria [65], four of the five classes of Proteobacteria [59,[66][67][68][69][70][71][72] as well as the yeast strains Saccharomyces cerevisiae [73] and Hansenula anomala [74]. These organisms interact with an anode through a variety of direct and indirect processes producing current to varying degrees.…”

Microbial Fuel Cells, A Current Review

Microbial fuel cells (MFCs) are devices that can use bacterial metabolism to produce an electrical current from a wide range organic substrates. Due to the promise of sustainable energy production from organic wastes, research has intensified in this field in the last few years. While holding great promise only a few marine sediment MFCs have been used practically, providing current for low power devices. To further improve MFC technology an understanding of the limitations and microbiology of these systems is required. Some researchers are uncovering that the greatest value of MFC technology may not be the production of electricity but the ability of electrode associated microbes to degrade wastes and toxic chemicals. We conclude that for further development of MFC applications, a greater focus on understanding the microbial processes in MFC systems is required.

“…Ringeisen et al (2006). Hansenula anomala gave 2.34 W/m 3 when graphite-felt was used as the anode material and deaerated suspension of nutrient broth in phosphate buffer was filled in anodic chamber (Prasad et al, 2007).…”

“…This gives the data of the redox potential that has happened in the anode compartment and also information about the direct electron transfer. For instance, the electrochemical activity of two enzymes has been demonstrated in a study where Hansenula anomala produced less peak currents when lactate has been added (Prasad et al, 2007).…”

The present study focuses on the bioelectricity production from pure culture of Bacillus tequilensis DMR-5 and Pseudomonas aeruginosa DMR-3. Both the cultures were isolated from the anodic biofilm of pre-run MFC's with rumen fluid as anodic substance. They were checked for the power production for 10 days both as pure isolates and co-culture. Bacillus tequilensis and Pseudomonas aeruginosa produced 250 mV and 20 mA, 310 mV and 10 mA respectively. Both these bacteria when used as mixed culture (110×10 5 CFU/mL) produced 450 mV and 40 mA. The biofilm of the anode was taken for cyclic voltammetry study and the oxidation and reduction peaks observed in both forward and reverse scan confirmed the electrochemical nature of the bacteria. Based on the power readings measured and cyclic voltammograms obtained, it has been found that the co-culture produced more power than the pure cultures when used individually in the Microbial fuel cell.

“…Optimization of the growth condition for dominant electrogenic bacteria would improve the power output. In addition, fungal strains were found to generate current, such as Saccharomyces cerevisiae (Walker and Walker Jr., 2006) and Hansenula anomala (Prasad et al, 2007), which were frequently found in soil. In our study, soil pH at the anode decreased during the 30 d and there may be a shift from bacteria to fungi.…”

Factors Affecting the Performance of Single-Chamber Soil Microbial Fuel Cells for Power Generation

et al. 2014

There is limited information about the factors that affect the power generation of single-chamber microbial fuel cells (MFCs) using soil organic matter as a fuel source. We examined the effect of soil and water depths, and temperature on the performance of soil MFCs with anode being embedded in the flooded soil and cathode in the overlaying water. Results showed that the MFC with 5 cm deep soil and 3 cm overlaying water exhibited the highest open circuit voltage of 562 mV and a power density of 0.72 mW m −2 . The ohmic resistance increased with more soil and water. The polarization resistance of cathode increased with more soil while that of anode increased with more water. During the 30 d operation, the cell voltage positively correlated with temperature and reached a maximum of 162 mV with a 500 Ω external load. After the operation, the bacterial 16S rRNA gene from the soil and anode was sequenced. The bacteria in the soil were more diverse than those adhere to the anode where the bacteria were mainly affiliated to Escherichia coli and Deltaproteobacteria. In summary, the two bacterial groups may generate electricity and the electrical properties were affected by temperature and the depth of soil and water.
