Light-induced formation of partially reduced oxygen species limits the lifetime of photosystem 1-based biocathodes

Nature Communications, 2018
Photobiodevices use photosynthetic proteins such as those of the photosystem 1 (PS1) to enable light-induced charge separation, but they suffer from limited long-term stability.

Enrichment of Marinobacter sp. and Halophilic Homoacetogens at the Biocathode of Microbial Electrosynthesis System Inoculated With Red Sea Brine Pool

Frontiers in Microbiology, 2019
Homoacetogens are efficient CO2 fixing bacteria using H2 as electron donor to produce acetate. These organisms can be enriched at the biocathode of microbial electrosynthesis (MES) for electricity-driven CO2 reduction to acetate.

Thermophilic biocathode with bilirubin oxidase from Bacillus pumilus

Electrochemistry Communications, 2013
Bilirubin oxidase (BOD) from Bacillus pumilus shows high thermostability in solution and high reactivity at high temperature for ABTS oxidation. When BOD is incorporated into a cross-linked redox-active hydrogel film consisting of pendant osmium moieties grafted on a polyvinylimidazole backbone on GC electrode, high catalytic current per enzyme ...

Analysis of bio-anode performance through electrochemical impedance spectroscopy [PDF]

, 2015
In this paper we studied the performance of bioanodes under different experimental conditions using polarization curves and impedance spectroscopy. We have identified that the large capacitances of up to 1 mF·cm− 2 for graphite anodes have their origin ...
