英文摘要	Harvesting of microalgae has been one of the major bottlenecks for commercial use. Sedimentation of the microalgae cells can facilitate the harvesting process, thus reducing the cost of yielding algae-based industrial products. We investigated the potential of Brachionus plicatilis and Anemia sauna culture filtrates for promoting Chiorella sedimentation. B. plicatilis culture filtrate demonstrated the potential for promoting Chiorella sedimentation, the sedimentation rate of Chiorella cells treated with the filtrate increased to 53.4 % within 24 h (20 % higher than control). The secretion of soluble extracellular polymeric substances was significantly increased in the Chlorella culture treated with either filtrate. The PSII quantum efficiency and growth rate in B. plicatilis culture treated Chiorella were not significantly affected. As the presented method is non-toxic and non-pathogenic, it may be an alternative for facilitating the harvesting of unicellular microalgae species used in the pharmaceutical sector and as food supplements.
