Abstract
|
The microbial community employed as biocatalyst in microbial fuel cells (MFC)
play a crucial role in degradation of organic substances and bioelectricity generation. While degradation of organic matters and electrical current generation in MFC
technology is predominantly depend on metabolic activities of electroactive bacteria
such as Geobacter and Proteobacteria, these bacteria engage in mutual interactions
with non-electroactive counterparts within the microbial community. These mutual interactions can modify system performance, which is widely depended on operational conditions, the source of the initial microbial inoculum, substrate diversityand system’s components. Consequently, it is essential to gain a comprehensive
understanding of the ecological behavior of microbial communities under diverse
conditions to optimize system efficiency. Numerous research studies have delved into
the microbial communities under varying circumstances, and the objective of this
research is to elucidate the distinctions among microbial communities and investigate
the factors that impact their composition.
