For biomass recovery of tropic ocean oleaginous microalgae strain Desmodesmus sp. WC08, eight flocculation methods (pH adjustment, Al2 (SO4)3, polyacrylamide, AlCl3, Ca (OH) 2, FeCl3, alum and chitosan) were evaluated and optimized. The results indicated that ferric chloride, aluminum sulfate, aluminum chloride and chitosan exhibited high flocculation ability and their flocculation efficiency were all beyond 94% at the optimal dosage (0.15, 0.4 and 0.03 gL-1, respectively). Chitosan displayed the most tremendous potential for biomass recovery from culture broth based on its feasibility and safety. Acetic acid and hydrous chloride, used to dissolving chitosan, had no significant difference in the flocculation efficiency. And when the pH of culture broth was set 5 or 6, the flocculation efficiency of chitosan was higher and the required flocculation time was.. View More»
