Abstract

Highlight Research S. platensis has been analyzed for its productivity. Analysis of the productivity of S. platensis on the use of fish culture wastewater media. S. platensis production can be increased by aquaculture wastewater. Aquaculture wastewater enhances the production of cell density, SGR, biomass, protein, and carotenoid of S. platensis. Abstract Increased productivity of Spirulina sp. in the form of high protein, carotenoids, and biomass content can be achieved by improving its nutrient supply. Inorganic fertilizers are nutrient sources, which are generally used in the culture of this organism on laboratory and industrial scale, but there are several drawbacks, including their high costs and limited availability. Several studies have also reported the use of zarrouk fertilizer as a standard culture medium for Spirulina platensis. Therefore, this study aims to determine the effect and the best concentration of fish culture wastewater treatment in Spirulina platensis culture using biomass, protein content, and carotenoid pigments as indicators. A two-factorial completely randomized designs (CRD) was used in this study, where the factors include the dose of organic waste and Zarrouk fertilizer. The microalgae samples, namely S. platensis were cultured using fresh water. This research consists of two factors. The first factor is the dose of organic waste, and the second factor is the dose of Zarrouk fertilizer. The wastewater treatment consisted of 0, 2, 4, and 6 ml/L, while Zarrouk dosages include 0, 0.5, and 1 ml/L. The best results were obtained from the sample treated with 6 ml/L aquaculture wastewater without the addition of Zarrouk. Furthermore, this treatment gave biomass production of 0.781 g/L, 50.441% protein, and 1.246 mg/L carotenoids. Based on the results, S. platensis culture can be carried out using fish culture wastewater without the addition of Zarrouk fertilizer.

养殖废水和Zarrouk对螺旋藻生物量、蛋白质和类胡萝卜素水平的影响

突出研究。对Platensis的生产力进行了分析。利用养鱼废水培养基对platensis生产力的影响分析[j]。利用养殖废水可提高Platensis的产量。养殖废水提高了platensis的细胞密度、SGR、生物量、蛋白质和类胡萝卜素的产量。摘要通过改善螺旋藻的营养供给，可以通过提高螺旋藻的蛋白质、类胡萝卜素和生物量来提高螺旋藻的生产力。无机肥料是一种营养来源，通常用于实验室和工业规模的这种生物的培养，但存在一些缺点，包括成本高和可用性有限。一些研究也报道了扎鲁克肥料作为螺旋藻标准培养基的使用。因此，本研究旨在以生物量、蛋白质含量和类胡萝卜素为指标，确定鱼类养殖废水处理在螺旋藻养殖中的效果和最佳浓度。本研究采用两因子完全随机设计(CRD)，其中影响因素包括有机废物和Zarrouk肥料的剂量。利用淡水培养微藻样品，即S. platensis。本研究包括两个因素。第一个因素是有机废物的剂量，第二个因素是扎鲁克肥料的剂量。废水处理为0、2、4和6 ml/L, Zarrouk剂量为0、0.5和1 ml/L。在不添加Zarrouk的情况下，用6 ml/L水产养殖废水处理的样品效果最好。此外，该处理的生物量产量为0.781 g/L，蛋白质产量为50.441%，类胡萝卜素产量为1.246 mg/L。综上所述，可以在不添加Zarrouk肥的情况下，利用养鱼废水进行平梭子鱼的培养。
