当利用微藻进行废水处理时，会遇到高成本和问题，例如流出物中的高细胞浓度。研究了海藻酸钙固定化小球藻GXNN 01在自养、异养、兼养和微氧条件下的脱氮除磷效果。固定化细胞在微好氧条件下的生长情况与自由细胞一样好，而在其他条件下的生长情况则优于自由细胞。固定化细胞具有较高的铵去除率分别为21.84%、43.59%和41.46（14.35%、38.57%和40.59%），对磷的去除率较高在异养、混合营养和微好氧条件下，活细胞的存活率分别为87.49%、88.65%和84.84%，而游离活细胞的存活率分别为20.21%、42.27%和53.52%。结果表明，固定化小球藻GXNN 01是一种较理想的废水处理菌种.

High costs and issues such as a high cell concentrations in effluents are encountered when utilizing microalgae for wastewater treatment. The present study analyzed nitrogen and phosphate removal under autotrophic, heterotrophic, mixotrophic and micro-aerobic conditions by Chlorella sorokiniana GXNN 01 immobilized in calcium alginate. The immobilized cells grew as well as free-living cells under micro-aerobic conditions and better than free-living cells under the other conditions. The immobilized cells had a higher ammonium removal rate (21.84%, 43.59% and 41.46%) than free living cells (14.35%, 38.57% and 40.59%) under autotrophic, heterotrophic, and micro-aerobic conditions, and higher phosphate removal rate (87.49%, 88.65% and 84.84%) than free living cells (20.21%, 42.27% and 53.52%) under heterotrophic, mixotrophic and micro-aerobic conditions, respectively. The data indicate that immobilized Chlorella sorokiniana GXNN 01 is a suitable species for use in wastewater treatment. (C) 2012 Elsevier Ltd. All rights reserved.
