The aim of this study was to investigate the cultivation of Nostoc sp., Arthrospira platensis and Porphyridium purpureum in industrial wastewater to produce phycobiliproteins. Initially, light intensity and growth medium composition were optimized, indicating that light conditions influenced the phycobiliproteins production more than the medium composition. Conditions were then selected, according to biomass growth, nutrients removal and phycobiliproteins production, to cultivate these microalgae in food-industry wastewater. The three species could efficiently remove up to 98%, 94% and 100% of COD, inorganic nitrogen and PO-P, respectively. Phycocyanin, allophycocyanin and phycoerythrin were successfully extracted from the biomass reaching concentrations up to 103, 57 and 30 mg/g dry weight, respectively. Results highlight the potential use of microalgae for industrial wastewater treatment and related high-value phycobiliproteins recovery.
本研究旨在探讨在工业废水中培养念珠藻、钝顶螺旋藻和紫球藻以生产藻蓝蛋白。最初，优化了光照强度和生长培养基组成，结果表明光照条件对藻蓝蛋白的生产影响大于培养基组成。然后根据生物量生长、营养物质去除和藻蓝蛋白生产选择条件，在食品工业废水中培养这些微藻。这三种微藻分别能有效去除高达 98%、94%和 100%的 COD、无机氮和 PO-P。从生物量中成功提取了藻蓝蛋白、别藻蓝蛋白和藻红蛋白，浓度分别高达 103、57 和 30mg/g 干重。研究结果突出了微藻在工业废水处理和相关高附加值藻蓝蛋白回收方面的应用潜力。
