introduction nowadays, energy, water and environmental issues are the intersection of all human’s requisites. supplying energy from a wide range of clean sources is a reliable response in order to obtain all of the requisites of mankind. salinity gradient power is a clean energy source that is available everywhere and has the capacity of supplying a reasonable amount of energy suitable to be us...

BACKGROUND Picophytoplankton (i.e. cyanobacteria and pico-eukaryotes) are abundant and ecologically critical components of the autotrophic communities in the pelagic realm. These micro-organisms colonized a variety of extreme environments including high salinity waters. However, the distribution of these organisms along strong salinity gradient has barely been investigated. The abundance and co...

Several approaches to generate electrical power directly from salinity gradient energy using capacitive electrodes have recently been developed, but power densities have remained low. By immersing the capacitive electrodes in ionic fields generated by exoelectrogenic microorganisms in bioelectrochemical reactors, we found that energy capture using synthetic river and seawater could be increased...
