Demonstration of MFC-fueled autonomous robot, EcoBot II
Bristol BioEnergy Centre will be showcasing the microbial fuel cell (MFC) technology at the ISMET conference and how this can be used to power a robot such as EcoBot-II. During the workshop, participants will have the opportunity to build an analytical size MFC (25 mL) and inoculate it with locally sourced inoculum in an attempt to learn more about MFC materials and prospects. In the meantime participants will use already colonised small-scale (6.25 mL) MFCs to power the EcoBot-II platforms and perform phototactic experiments with the use of a torch. During the workshop a selection of different MFC designs and materials (non-contaminated) that have been explored so far by BBiC will be presented as well.
Duration: 2 hours

Pavlina Theodosiou is a research associate at Bristol Bioenergy Centre (University of the West of England, Bristol) working on the PeePower™ technology. Her current project is funded by OXFAM and focuses on implementing the PeePower™ in refugee camps and slums in the developing world. Her PhD was funded by the European Commission under the project name EVOBLISS (FP-7) and she conducted her work at University of the West of England under the supervision of Prof. Ioannis Ieropoulos. For her thesis Pavlina was working with the robotic platform EvoBot, a 3D-printer turned to robot, which she used as an automated Robot-Chemostat for culturing and maintaining Microbial Fuel Cells. The improved MFCs were then used on board the 2018 edition EcoBot-II. For this workshe was awarded the “Best Biology Paper” at the 6 th Living Machines Conference in StanfordUniversity.
Reactors for microbial electrochemistry
Description: In this workshop, a detailed overview of the different types of reactors that have been used over the years for different applications will be given. This will include the reactors for basic research including those used for investigating the electron transfer mechanism in bioelectrochemical systems (BESs). Reactors type for applied microbial electrochemical technologies (METs) such as Microbial Fuel Cell (MFC) (evolution over the years) will be discussed. The pilot studies carried out using MFCs will also be presented. Reactors used for Microbial electrolysis cells (MECs) for hydrogen production will be presented from both intial lab-scale ones to present pilots. Reactors for microbial electrosynthesis (MES) for cathodic production of chemicals (mainly using CO2 as feedstock) and their design including upscaling challenges will be discussed. A brief discussion on other emerging METs like microbial desalination cell (MDCs) and bioelectrochemical sensosrs will also be presented. An overview of the main components including anode materials, cathode materials and membranes/separators will also be held.

Wisely using electrochemical methods and deciphering thermodynamic fundamentals of microbial metabolism
Description: This course comprises two distinguished thematic blocks:
In the first part, the basics of electrochemistry and electrochemical methods will be explained.
Thereby, it will be focused on three-electrodes-setup, reference electrodes, cyclic voltammetry
(CV) and the acquisition of power curves. Further as a prime example cultivation of biofilm anodes, performing CV and interpretation of the analysed data will be presented. Subsequently, this basic knowledge is used to illustrate the difference between MFC and MEC and to discuss
troubleshooting of experimental setups. Finally, derived (bio)electrochemical parameters and their
significance will be critical discussed.
The second part of the course focuses on microbial thermodynamics and comprises theoretical
aspects as well as calculation exercises. In the beginning, the fundamentals of microbial energy
harvest and the basic principles of thermodynamics will explained, followed by example
calculations on microorganisms respiring soluble electron acceptors. These examples include
principles for establishing chemical equations in a biochemical context, Gibbs free energy
calculations as well as the transformation in potential calculations. Subsequently, the pecularity of
the energy harvest of electroactive microorganisms is discussed and the consequences on
thermodynamic calculations are exemplified.
Duration: two half days (each 3-4h) respectively one day with 6-8h

Biofilm fundamentals and electrochemical detection of early biofilm formation
Description: Biofilms are microstructured microbial communities living at interfaces. Biofilms can be described as complex bug megalopolis, with an intricate network of signals and physicochemical interactions. This is especially true for mixed consortia biofilms, where interactions between different species must be considered. Biofilms have emerging properties that are different from those of single microorganisms, such as resistance to antimicrobial agents, nutrients/metabolites storage and strong chemical gradients, which determine the metabolic activity at different depths in the biofilm. The high concentration of microorganisms in biofilms make them ideal for biodegradation and energy conversion in bioelectrochemical systems.
In the first part of this workshop, we will review the fundamental concepts needed for qualitative and quantitative understanding of biofilms in laboratory systems, including methods for biofilm growth and monitoring. In the second part, we will discuss the early stages of biofilm formation and the electrochemical signature of early biofilms on microstructured/nanostructured materials. This is particularly relevant to rapid screening of electrogenic microorganisms, both in pure species and mixed microbial consortia, and to the development of bioelectrochemical sensor. As a practical example, the early attachment of weak electroactive biofilm will be monitored in potentiostat-controlled electrochemical cells and the biofilm formation will be detected through Electrochemical Impedance Spectroscopy.
