Exoelectrogens for microbial electrochemical technologies: temperature dependence, energy harvesting, and remediation Universiteit Hasselt
A 96-channel 40nm CMOS potentiostat for parallel experiments on microbial electrochemical systems Universiteit Gent KU Leuven
Monitoring microbial electrochemical processes in a time-and cost-efficient manner requires multi-channel potentiostats with the capability to control each channel towards a unique targeted potential. State-of-the-art (SotA) PCB potentiostats cannot perform high-frequency analysis due to their limited bandwidth. Existing integrated CMOS potentiostats on the other hand enable higher sensing channel density with a high bandwidth, yet are still ...
Microbial protein production from methane via electrochemical biogas upgrading Universiteit Gent
Microbial protein (MP) can alleviate the increasing pressure of food demand on agriculture and our environment. For its sustainable production, feedstocks such as biomethane or (bio)hydrogen are needed. Here, we coupled biogas produced from agricultural waste directly with electrochemical biogas upgrading to subsequently produce MP from methane, hydrogen or a mixture thereof. Biogas was produced from co-digestion of pumpkin and pig manure at ...
Direct electrochemical extraction increases microbial succinic acid production from spent sulphite liquor Universiteit Gent
The fermentative production of succinic acid leads to increasing toxicity over time, and requires base addition to counteract acidification. Here we integrated a fed-batch Basfia succiniciproducens succinic acid fermentation with membrane electrolysis. This approach brings the broth in direct contact with an OH- and H-2 producing cathode, and enables in situ extraction of succinate towards the low volume H+ and O-2 producing anode compartment. ...
Electrochemical ammonia recovery from source-separated urine for microbial protein production Universiteit Gent

Assessment of the microbial community in the cathode compartment of a plant microbial fuel cell Universiteit Gent
Introduction: In plant microbial fuel cells (plant-MFCs) living plants and microorganisms form an electrochemical unit able to produce clean and sustainable electricity from solar energy. It is reasonable to assume that besides the bacteria in the anode compartment also the cathode compartment plays a crucial role for a stable high current producing plant-MFC. In this study we aim to identify dominant bacterial species in the cathode compartment ...
