Abstract:
Microbial fuel cells (MFC) constitute a new technological approach, that’s still in development, for wastewater treatment, electricity generation and for bio-hydrogen generation. These types of fuel cells use microorganisms as bio-catalysts. Practically the chemical energy is transformed in electrical energy using bacteria such as Escherichia coli or Saccharomyces. A typical MFC shares many similarities with chemical fuel cells such as direct ascorbic acid fuel cells and direct methanol fuel cells. Therefore, an attempt is made to develop a MFC model similar to chemical fuel cells that can be applicable in large scales. This paper highlights the research made until know on scalling up this systems for wastewater treatment applications and presents different kinds of models used to purify water. We also have a preliminary study on MFC model based on a two-chamber configuration having as microbial community - a pure culture of Saccharomyces cerevisiae. We researched the capacity of the typical MFC to produce power density, to remove organic matter, and to observe the microbial community behavior in a steady state operation by measuring pH, conductivity, dissolved oxygen and organic matter removal.
