Ecological responses to substrates in electroactive biofilm: A review

Ecological responses to substrates in electroactive biofilm: A review Substrate as the electron donor of bioelectrochemical system (BES) has fateful impacts on the microbial community composition of electroactive biofilm (EAB), via the selection upon functional microorganisms such as exoelectrogens, fermenters and methanogens, as well as their interactions. Electrochemical performance as the terminal reflects of electroactivity and the correspondence between community members have been summarized. Exoelectrogens responsible to the conversion towards electricity from their respective preferred substrates such as acetate, propionate, glucose and cellulose has been found to be finite in a small range, e.g., Geobacter, Shewanella and Pseudomonas. Their demands of micromolecular electron donors and the selective pressure of primary substrates facilitate the existence of competitive or cooperative biological processes to exoelectrogenesis.

Abstract

Substrate as the electron donor of bioelectrochemical system (BES) has fateful impacts on the microbial community composition of electroactive biofilm (EAB), via the selection upon functional microorganisms such as exoelectrogens, fermenters and methanogens, as well as their interactions. Electrochemical performance as the terminal reflects of electroactivity and the correspondence between community members have been summarized. Exoelectrogens responsible to the conversion towards electricity from their respective preferred substrates such as acetate, propionate, glucose and cellulose has been found to be finite in a small range, e.g., Geobacter, Shewanella and Pseudomonas. Their demands of micromolecular electron donors and the selective pressure of primary substrates facilitate the existence of competitive or cooperative biological processes to exoelectrogenesis. The inherent mechanisms of the dynamics of such interactions have been explored with electrochemical methods, defined co-culture experiments and community analysis. Complete view of the metabolic network in electroactive microbial communities has been shed light on, and appeals further investigation.
