Description
Summary:Microbial mutualistic interaction or synthetic microbiology evolves closely from the concept of cell-cell relations in a complex microbial community, which plays a crucial role in waste degradation, bioremediation, and bioenergy generation. Recently, the application of synthetic microbial consortia has renewed attention in the field of bioelectrochemistry. In the past few years, the influence of microbial mutualistic interaction has been extensively studied in bioelectrochemical systems (BES), especially in microbial fuel cells (MFCs). Nevertheless, synthetic microbial consortia were found to exhibit superior bioremediation performance compared to single strains of microbes for polycyclic aromatic hydrocarbons, synthetic dyes, polychlorinated biphenyls, and other organic pollutants compared to the respective single microbial species. However, a comprehensive understanding of intermicrobial interactions, specifically the metabolic pathways in a mixed-cultured microbial community system, is still lacking. In this study, we have comprehensively reviewed the possible pathways for executing intermicrobial communication within a complex microbial community consortium with various underlying pathways. The influence of mutualistic interactions on the power generation of MFCs and wastewater biodegradation has been widely reviewed. We argue that this study would motivate the design and construction of potential synthetic microbial consortia to stimulate the extraction of bioelectricity and the biodegradation of contaminants.
