论文摘要
这项研究的目的是研究工业废水中的Nostoc sp。，关节螺旋体铂和紫pupureum的培养以产生植物脂蛋白。最初，优化了光强度和生长培养基成分，表明光条件对植物蛋白的产生影响更大，而不是中等成分。然后根据生物量的生长，去除营养和植物脂蛋白的产生，选择条件，以在食品引入的废水中培养这些微藻。这三个物种可以有效地删除高达98％，94％和100％的鳕鱼，无机氮和PO43--P。分别从生物量中取出的植物素，阿叶藻蛋白酶和植物蛋白分别从最高103、57和30 mg/g干重的生物质中提取。结果突出了微藻对工业废水处理的潜在用途和相关的高价值植物蛋白恢复。
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 PO43--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.
