Effect of β-cyclodextrin/polydopamine composite modified anode on the performance of microbial fuel cell
Article
Full-text available
  • May 2022
The relatively weak microbial adhesion is a bottleneck in improving the power generation performance of microbial fuel cell (MFC). Anode modification is a simple and effective method to solve this problem. A new type of β-cyclodextrin/polydopamine modified carbon felt anode was prepared, and the effects of β-cyclodextrin/polydopamine modified anode...

... Both of these compounds' advantageous properties have already been mentioned, but in this combination, polydopamine provides hydrophilicity and superior adhesive force, while rGO offers electrochemically active sites for improved electron transfer, resulting in a 6-fold increase in power density to about 2 W m −2 . Further, Fan and Xi (2022) combined polydopamine with β-cyclodextrin for 4.6-fold increase in power density. β-cyclodextrin affects fluidity and permeability of biofilms by inducing lipid exchange between cells (Hammoud et al., 2019). ...
Microbe–Anode Interactions: Comparing the impact of genetic and material engineering approaches to improve the performance of microbial electrochemical systems (MES)

  • Feb 2023
Microbial electrochemical systems (MESs) are a highly versatile platform technology with a particular focus on power or energy production. Often, they are used in combination with substrate conversion (e.g., wastewater treatment) and production of value‐added compounds via electrode‐assisted fermentation. This rapidly evolving field has seen great improvements both technically and biologically, but this interdisciplinarity sometimes hampers overseeing strategies to increase process efficiency. In this review, we first briefly summarize the terminology of the technology and outline the biological background that is essential for understanding and thus improving MES technology. Thereafter, recent research on improvements at the biofilm–electrode interface will be summarized and discussed, distinguishing between biotic and abiotic approaches. The two approaches are then compared, and resulting future directions are discussed. This mini‐review therefore provides basic knowledge of MES technology and the underlying microbiology in general and reviews recent improvements at the bacteria–electrode interface.
