The growth of aquaculture depends on protein sources that can reduce the pressure on fishmeal (FM), and Spirulina feed could be an option due to its high nutritional value. Studies on Spirulina as a food in diets of aquatic organisms have increased substantially in the past decade, but the fact that its use in commercial rations does not occur today indicates that there are still challenges that need to be overcome. This review attempts to compile most of the work carried out through today in aquaculture that uses Spirulina as an FM substitute and as a functional feed. The high cost of Spirulina can be compensated if it is used in small quantities because it can improve the health and growth of organisms, compensating for its high economic cost by reducing costs in other production areas. 1369 The use of Spirulina in aquaculture diets RI, GI Kohal et al.

IntroductionAs a pigment protein, phycocyanin has been widely used in the fields of food, nutraceutical and biotechnology due to its excellent biological activities of antioxidant. So far, Arthrospira has been generally considered as a great species for phycocyanin production.MethodsIn this study, independent and interactive effect of three factors, NaCl, Bainengsi (BS) and Bainengtai (BT) on microalgae growth and phycocyanin production were explored by response surface methodology (RSM). Using Box-Behnken design (BBD) method, the well-fitting quadratic models were established based on experimental results.ResultsMoreover, the maximum phycocyanin concentration reached 704.66 mg L-1 at the optimal condition (185 mM NaCl, 200 mg L-1 BS, and 20 mg L-1 BT), while the maximum phycocyanin content of 19.03% was obtained at another optimal condition (136 mM NaCl, 200 mg L-1 BS, and 50 mg L-1 BT). Compared to control, the concentration and content of phycocyanin were increased by 22.98% and 16.73%, respectively.DiscussionOverall, this study demonstrated that addition of exogenous substances (BS, BT) into culture medium optimized by RSM was an effective approach to increase phycocyanin production, which paved a potential way to realizing high efficient production of algal biomass and bioactive substances.

“…To obtain the maximum amount of the target pigment and to reduce the production cost in the initial stage, the selection of a suitable cell wall disruption method and a buffer solution for the C-PC extraction was crucial. The extraction was performed according to the method described by Khazi et al [20]. Five ml of culture centrifuged for 5 min at 10,000 rpm.…”

The physicochemical characteristics of phycocyanin extracted from cyanobacteria collected in Kaunas Lagoon were studied (spectrum characteristics, C-PC content in the dry mass and chemical purity). It was determined that the tested concentrations of C-PC in purified water should be in the range of 0.02–0.16% for measuring C-PC content in the dry mass and its spectrum characteristics. The two clear absorption maxima were detected in the spectrum of C-PC at the wavelengths of 277 and 619 nm. The content of C-PC in the dry powder form was in the range of 7.25% to 9.30% depending on its concentration in the solution and type of spectrophotometer. Furthermore, a purity factor of 1.5 was calculated, which indicated the food qualification of the obtained biomass of C-PC. Finally, the analytical procedure for studying the pro- and anti-oxidant activity of C-PC was developed and the antioxidant activity of C-PC was measured for the available markers. It was revealed that C-PC has dual properties (pro- and anti-oxidant ones) depending on its concentration, more exactly, its content in reaction mixtures with 2,2-diphenyl-1-picrylhydrazyl (DPPH). The following issues were resolved during the research: the concentration of ethanol in the DPPH solution was chosen in order to avoid precipitation of proteins in the reaction mixtures (50%); the ratio of the solution of C-PC to the DPPH solution was selected; the selected concentrations of the markers for the construction of their calibration curves were chosen for quercetin and for rutin. The antioxidant activity of the obtained C-PC sample was determined. Keywords: antioxidant activity, C-phycocyanin, cyanobacteria, DPPH, quercetin, rutin
