“…In the literature there are reports of several extraction methods, which combine different steps. Besides quantity, quality is strongly influenced by the selection of the appropriate extraction method (SASSANO et al, 2004;MATSUDO, 2009;MARKOU, 2012;LU et al, 2018;SHANTHI;PREMALATHA;ANANTHARAMAN, 2018;MAO;GUO, 2018;İLTER et al, 2018).…”

Phycocyanins are water-soluble proteins that work as accessory pigments and have several properties, such as immunostimulant action, cholesterol reducing effect, anti-inflammatory, antiviral, anticancer, antioxidant effects, among other uses. This study aimed to evaluate the accumulation of phycocyanin and biomass production of the microalgae Arthrospira (Spirulina) platensis grownin fish effluent. The experiment was carried out in two phases. The first developed in an indoor environment with controlled conditions, while the second, in a recirculation system, in an outdoor environment, using for both phases the Venkataraman media (control) and Nile tilapia effluent. There was no significant difference (p>0.05) between the performance of algae grown under the same conditions. Phycocyanin concentrations were higher for the treatments using modified Venkataraman medium. The purification process by ion exchange chromatography resulted in higher pigment concentrations for the eluted fractions with 0.2 M NaCl for all crude phycocyanin extracts.

“…Thus, the presence of several nitrogen sources present in the wastewater, such as urea, nitrate, ammonium, tryptone or yeast extract, can increase the lipid yield. The metabolic shift from membrane biosynthesis to lipid cell storage synthesis can cause an increase in lipid content under low nitrogen content (Shanthi et al, 2018).…”

Inadequate wastewater management can cause negative impacts on the ecosystem, becoming an obstacle to aquaculture growth. New technologies have been developed to reduce the nutrient load in aquaculture wastewater involving microalgae as phytoremediation agents. In addition to reducing the nutrient load of water bodies, the microalgae‐based phytoremediation can also generate high‐added value biomass. Arthrospira (Spirulina) is a little‐explored genus as a phytoremediation agent for aquaculture wastewater, representing about 30% of the biomass produced in the world that is known for its high concentration of proteins, carotenoids and phycocyanin. Using the aquaculture wastewater is an important strategy to reduce the production costs, obtain high‐added value biomolecules and mitigate the effects of wastewater on the aquatic ecosystem. However, there are few reports of Arthrospira sp. as a remediation agent for aquaculture wastewater that assesses the biochemical composition. This manuscript aimed to review the cellular mechanisms of phytoremediation and the biochemical composition of Arthrospira currently described when grown in aquaculture wastewater.

“…Spirulina platensis tidak dapat memfiksasi N dari udara karena tidak memiliki heterosis, sehingga pemenuhan kebutuhan N sangat bergantung pada ketersediaannya di dalam media tumbuh (Rina et al, 2017). Spirulina platensis dapat mengasimilasi berbagai bentuk sumber N termasuk NO3 -, NH4 + , N-organik seperti urea dan asam amino (Kim et al, 2016;Shanthi et al, 2018).…”

The need of nitrogen (N) for the growth of Spirulina platensis and the production of protein and phycocyanin pigment is influenced by the type of source and the concentration of N contained in the growing media. Spirulina platensis can assimilate various N sources, including nitrate (NO3-) and urea. Urea is a cheap N source and easy to be obtained. Urea can also have a role as potential N source to support the growth and the metabolites production of cyanobacteria S. platensis. Partial substitution of N source (NO3‑) to urea in Zarrouk medium for S. platensis cultivation has not been conducted before. This study was aiming at determining the optimum ratio of NaNO3 : CO(NH2)2 and the optimum N concentration in the Zarrouk medium for protein and phycocyanin production by S. platensis. Response Surface Method (RSM)-one factor experimental design was employed in this study for determining the optimum N concentration at specific N concentration range and optimum ratio of N source that had been previously determined. The results demonstrated that the optimum ratio of NaNO3 : CO(NH2)2 for protein and phycocyanin production was 1:1. The optimum N concentration for protein and phycocyanin pigment production in S. platensis cultivation were 5.13 mmol L-1 and 4.94 mmol L-1 with the increament in about 51.95% and 25.16%, respectively, compared to the standar Zarrouk medium.Kebutuhan unsur nitrogen (N) untuk pertumbuhan Spirulina platensis serta produksi protein dan pigmen fikosianin dipengaruhi oleh jenis sumber dan konsentrasi N yang terkandung dalam media tumbuh. Spirulina platensis dapat mengasimilasi berbagai sumber N, termasuk nitrat (NO3-) dan urea. Urea merupakan sumber N yang murah dan mudah diperoleh. Urea juga dapat berperan sebagai sumber N potensial untuk mendukung pertumbuhan dan produksi metabolit pada sianobakteria S. platensis. Substitusi sebagian sumber N (NaNO3) oleh urea dalam media Zarrouk untuk kultivasi S. platensis belum banyak dilakukan sebelumnya. Penelitian ini bertujuan untuk menentukan nisbah NaNO3 : CO(NH2)2 dan konsentrasi N optimum yang diperlukan dalam media Zarrouk untuk produksi protein dan fikosianin oleh S. platensis. Desain eksperimen RSM-one factor digunakan dalam penentuan konsentrasi N optimum pada rentang konsentrasi N dan nisbah sumber N optimum yang telah ditentukan sebelumnya. Hasil penelitian menunjukkan bahwa nisbah NaNO3 : CO(NH2)2 optimum untuk meningkatkan kandungan protein dan pigmen fikosianin S. platensis adalah 1:1. Konsentrasi N optimum untuk produksi protein dan pigmen fikosianin pada kultivasi S. platensis ialah 5,13 mmol L-1 dan 4,94 mmol L-1 dengan peningkatan sebesar 51,95% dan 25,16%, secara berturut-turut, bila dibandingkan dengan saat dikultivasi menggunakan media Zarrouk standar.
