Spectroelectrochemical analyses of electroactive microbial biofilms.
Understanding the mechanism of ET (electron transfer) through electroactive microbial biofilms is a challenge in the field of fundamental and applied life sciences. To date, electrochemical techniques such as CV (cyclic voltammetry) have been applied successfully to study the ET process in intact microbial biofilms on electrodes, providing important insight into their redox properties. However,...
متن کاملDevelopment of Electroactive and Anaerobic Ammonium-Oxidizing (Anammox) Biofilms from Digestate in Microbial Fuel Cells
Microbial Fuel cells (MFCs) have been proposed for nutrient removal and energy recovery from different wastes. In this study the anaerobic digestate was used to feed H-type MFC reactors, one with a graphite anode preconditioned with Geobacter sulfurreducens and the other with an unconditioned graphite anode. The data demonstrate that the digestate acts as a carbon source, and even in the absenc...
متن کاملUnravelling biocomplexity of electroactive biofilms for producing hydrogen from biomass
Leveraging nature's biocomplexity for solving human problems requires better understanding of the syntrophic relationships in engineered microbiomes developed in bioreactor systems. Understanding the interactions between microbial players within the community will be key to enhancing conversion and production rates from biomass streams. Here we investigate a bioelectrochemical system employing ...
متن کاملAn Electrochemical Strategy to Measure the Thickness of Electroactive Microbial Biofilms
The study of electroactive microbial biofilms often requires knowledge of the biofilm thickness. Unfortunately, this parameter is, nowadays, only accessible through expensive microscopic techniques. This work overcomes this limitation by presenting a new strategy, exploiting the use of chronoamperometry (CA) alone. A mixed-culture biofilm is exposed to an O2-saturated solution during anode resp...
متن کاملWaste Water Derived Electroactive Microbial Biofilms: Growth, Maintenance, and Basic Characterization
The growth of anodic electroactive microbial biofilms from waste water inocula in a fed-batch reactor is demonstrated using a three-electrode setup controlled by a potentiostat. Thereby the use of potentiostats allows an exact adjustment of the electrode potential and ensures reproducible microbial culturing conditions. During growth the current production is monitored using chronoamperometry (...
