Microbial carbon capture cells (MCCs) were constructed with cyanobacteria growing in a photo biocathode in dual-chambered flat plate mediator-less MFCs separated by an anion exchange membrane from the anode compartment containing Shewanella putrefaciens. The performance of the MCC with Anabaena sparged with CO2-air mixture was compared with that of a conventional cathode sparged with air only. The power densities achieved were 57.8 mW/m(2) for Anabaena sparged with a CO2-air mixture, 39.2 mW/m(2) for CO2-air mixture sparging only, 29.7 mW/m(2) for Anabaena sparged with air, and 19.6 mW/m(2) for air sparging only. The pH of the cathode containing Anabaena gradually increased from 7 to 9.12 and power generation decreased-from 34.7 to 23.8 mW/m(2) 17 due to pH imbalance associated voltage losses without CO2-air mixture sparging. Sparging with a 5% CO2-air mixture produced maximum power of 100.1 mW/m(2). In addition, the power density of MCC increased by 31% when nitrate was added into the catholyte. (C) 2011 Elsevier Ltd.
