Electrocoagulation is an evolving technology that has been effectively applied for wastewater treatment but its applications in biotechnology and nanotechnology are very limited. This method was applied for the preparation of nanoparticles from soluble exopolysaccharide (EPS) produced by Claviceps viridis in a submerged batch culture. A cathode/anode pair electrode (Al or Fe) system was used for determination of the separation rates of electrocoagulation and the yields of EPS nanoparticles production. The separation rates of 0.170 +/- 0.003 mg EPS/sec (Fe electrodes) and 0.250 +/- 0.003 mg EPS/sec (Al electrodes) were calculated for voltage gradient 1 V/1 cm of electrodes distance and were constant during experiments. The specific yield of EPS nanoparticles production based on the consumed electric power was dependent on the material of the electrodes and its value was determined as 0.71 +/- 0.01 mg EPS/W for Fe electrodes and 0.91 +/- 0.01 mg EPS/W for Al electrodes, respectively.
