Energy-producing electro-flocculation for harvest of Dunaliella salina.

abstract：:One of the hurdles of renewable energy production from photosynthetic microorganisms is separating the biomass from water in cultures. Bioflocculation with filamentous fungus Aspergillus niger, an alternative low-cost method used for such separation, was studied with four cyanobacteria. Cocultures with Spirulina maxim...
