Abstract
In present study, bioelectrochemical degradation of oxalate as a substance which its concentration in kidney leads to urolithiasis in a microfluidic microbial fuel cell (MFC) was investigated. In addition, to define a novel application for the microfluidic MFC, measurement and monitoring of oxalate concentration were studied. This application can introduce the system as an implantable medical device for medical usage of urolithiasis and hyperoxaluria diseases. In this work, by designing and fabrication of two MFCs including a large-scale and microfluidic one, and measuring the outlet concentration of oxalate in the large-scale system, the outlet concentration of oxalate at microfluidic MFC...
The Fabrication of the Coupled Microfluidic Microbial Electrochemical Cells for Oxalate Biodegradation
, M.Sc. Thesis Sharif University of Technology ; Yaghmaei, Soheila (Supervisor) ; Mardanpour, Mohammad Mahdi (Co-Supervisor)
Abstract
This study invewstigates the performance of a coupled microfluidic microbial fuel cell-microbial electrolysis cell producing biohydrogen in presence of shewanella oneidensis MR-1 from excreted oxalate of human metabolic processes. The effect of different parameters such as cell geometry including spiral and straight microchannels, precipitation of nano-particles on anode surface, substrate flowrate and the number of microfluidic microbial fuel cell supporting required power for microbial electrolysis cell were assessed. By anode modification, the maximum current density of 428 W m-3 was obtained which is less than 6-fold of the maximum power density in the cell fabricated by zinc foil. The...
