N2  - In this study, the extracellular polymeric substance of Scenedesmus quadricauda called EPS-S.q and its bioflocculatoin mechanism were investigated. Results showed EPS-S.q was successfully used as bioflocculating agent for S.� quadricauda biomass harvesting and flocculation efficiency of up to 86.7 to S.� quadricauda cells could be achieved in presence of Zn2+. EPS-S.q was the flocculating agent for self-flocculating microalga S.� quadricauda and bioflocculation mechanism was polymer bridging. The sugar and protein mass fraction of dry EPS-S.q was sugar 56.7 and protein 41. The infrared spectrum further indicated the presence of hydroxyl, carboxyl and amino groups. Moreover, pH decrease induced the flocculation of S.� quadricauda and 78.4 of flocculation efficiency was the highest at pH 3. In addition, chemical flocculant FeCl3 was efficiently used for S.� quadricauda harvesting and up to 96.8 of flocculation efficiency could be achieved for S.� quadricauda culture with biomass concentration 0.21�??0.39� g� L�??1 at pH 7. © 2016
