Abstract The objective of this study was to integrate the treatment of aquaculture effluent with the biomass and macronutrients production by Spirulina sp. LEB 18. The first experiment was carried out in a photobioreactor (1 L) and the best biomass production condition was reproduced on a pilot scale in a raceway type bioreactor (5 L). The best treatment was T25 (100% of wastewater supplemented with 25% of Zarrouk nutrients). The biomass production in the raceway system (T25) was higher (3.33 g L−1) than the control (2.32 g L−1) and the carbohydrate (69.77%) and lipid (12.77%) were also higher. The content of carotenoids in T25 was significant (9.68 μg mL−1). Spirulina sp. LEB 18 removed phosphate (99.97%); COD (89.34%) and nitrate (81.10%) from aquaculture effluent. The effluent showed absence of heavy metals and concentration of Al; Fe; Ca and Mg higher than the control culture with Zarrouk nutrients. The Spirulina sp. LEB 18 can be applied as a bioremediation agent of aquaculture wastewater with high production of biomass, carbohydrate, lipid and carotenoid.

螺旋藻 使用水产养殖废水在室外中试规模的 LEB 18 养殖：高生物量、类胡萝卜素、脂质和碳水化合物生产

摘要 本研究的目的是将水产养殖废水的处理与螺旋藻的生物量和常量营养素生产结合起来。LEB 18. 第一个实验在光生物反应器 (1 L) 中进行，最佳生物质生产条件在跑道型生物反应器 (5 L) 中以中试规模重现。最好的处理是 T25（100% 的废水补充 25% 的 Zarrouk 营养素）。跑道系统 (T25) 中的生物质产量 (3.33 g L-1) 高于对照 (2.32 g L-1)，碳水化合物 (69.77%) 和脂质 (12.77%) 也更高。T25 中类胡萝卜素的含量显着（9.68 μg mL-1）。螺旋藻 LEB 18 去除磷酸盐 (99.97%)；水产养殖废水中的 COD (89.34%) 和硝酸盐 (81.10%)。流出物显示不含重金属和铝浓度；铁；Ca 和 Mg 高于含有 Zarrouk 营养物的对照培养物。螺旋藻。LEB 18 可用作水产养殖废水的生物修复剂，可高产生物量、碳水化合物、脂质和类胡萝卜素。
