【 摘 要 】

Electrogenic microalgae attached on cathode could enhance the generation of current in microbial fuel cells. For understand the electrochemical characterizations of microalgae, Desmodesmus sp. A8, as a model electrogenic microalgae, was investigated by cyclic voltammetry analysis under illumination and dark. Desmodesmus sp. A8 showed higher current response under incandescent (4.46 μ A) than that under fluorescent (2.16 μ A) at -0.44 V vs. Ag/AgCl, while the current decreased significantly to 0.14 μ A in dark. With the increasing illumination time, current generation enhanced rapidly and reach to a certain value remained stable, finally. From the light source and working time, we demonstrated that light profoundly impacted the electricity generation of electrogenic microalgae Desmodesmus sp. A8.
