Elucidating the bio-electrochemical mechanism of exoelectrogenesis of the cyanobacterium Synechocystis sp. PCC6803
Isolated chloroplasts (from plants and algae) and photosynthetic microorganisms, including algae and cyanobacteria, can export electrons/reducing equivalents upon illumination in a phenomenon called ‘exoelectrogenesis’. Biophotovoltaic systems (BPVs) are devices in which exoelectrogenesis of …

An Integrated Approach to Improving Efficiency in Photosynthetic Microbial Systems
… bioenergy and bioproducts. As cyanobacteria are photosynthetic microorganisms, they only require sunlight, carbon dioxide, nutrients, and water to grow, and can be cultivated using non-arable land and non-potable water. These characteristics, along with their rapid growth rates and amenability to …
