Alcina; Sleutels, Tom; Hamelers, Bert; ter Heijne, AnnemiekSupplementary material associated with this article can be found, in the online version, at doi: 10.4121/57265539-f6f7-411a-9b2f-f84dbec7cdda.; The accumulation of electrons in the form of Extracellular Polymeric Substances (EPS) and poly-hydroxyalkanoates (PHA) has been studied in anaerobic processes by adjusting the access of microorganisms to the electron donor and final electron acceptor. In Bio-electrochem...
Investigating bacterial community changes and organic substrate degradation in ...
Barbosa, Sónia G.; Peixoto, L.; ter Heijne, Annemiek; Kuntke, P.; Alves, M. M.; Pereira, M. AlcinaThe present study investigates the changes in the microbial community and the degradation of organic compounds in a microbial fuel cell (MFC) operated on human urine. An anaerobic community was enriched in urine-degrading electroactive microorganisms by stepwise lowering the dilution factor of the anode media from 50 times diluted to undiluted urine. In a duplicated assay a current density of 495±16 mA m-2, a c...
Effect of different carbon materials on the performance of microbial electrolys...
Barbosa, Sónia Glória Linhares; Peixoto, L.; Soares, Olivia S. G. P.; Pereira, Manuel Fernando R.; ter Heijne, Annemiek; Kuntke, Philip; Alves, M. M.ISMET 6 - General Meeting of the International Society for Microbial Electrochemistry and Technology; Urine is rich in nitrogen and phosphorous and can considerably reduce domestic wastewater treatment requirements if collected separately. Source separated urine has been shown to be suitable for energy production and nutrients recovery in bioelectrochemical systems. However, there are still several challenges t...
