Studies on marine microbial fuel cell

Abstract

The chemical process that bacteria utilize to shift electrons to their neighboring environments are assorted and not well understood. This study provides novel information that initiate to reveal correct mechanisms involved with electron transfer to microbial fuel cell (MFC) electrodes using various bacterial isolates. In the present study, effect of varied salt and carbohydrate (dextrose) concentration was studied in a novel MFC design was observe. In the optimal salt concentration, the MFC produced a maximum current of 262 µA and in optimum concentration of dextrose a maximum of 1033mV. The various combinations of bacterial isolates were also studied and found that they are much more efficient in generating high potential difference. These data have implication toward the optimization of bioremediation technologies, MFC advancement and to the basic understanding of how bacteria work together with their environments. This determines the choice and performance of specific organisms.
