This research aimed to compare effects on product quality and algal growth of inoculation ratio of Arthrospira platensis in the culture medium containing 20% geothermal water. A. platensis was inoculated at the ratio of 1/6, 1/10, and 1/20 of nutrient medium volume (2500 mL). The experiment medium was prepared with 20% geothermal water and 80% distilled water. Schlösser medium, 100% geothermal water medium, and 100% distilled water were used as the control group. At the end of the experiment, Spirulina biomass was obtained by filtration through 80-micron plankton cloth and freeze-dried at -60 °C. Increasing inoculation density shortened the culture time and increased the growth rate compared to the other groups. The best growth among the experimental groups was obtained in a 1/6 ratio inoculated Spirulina group in a 20% geothermal water medium. Among the experimental groups, dry biomass was obtained in the Spirulina group inoculated at 1/6 in only 20% geothermal water medium. The optical density value was 0.989 (A750), and the biomass yield was 0.476 g/L in the experimental group, the highest among the Schlösser groups was 1.259 (A750), and the biomass yield was 0.928 g/L. The most efficient growth and phycocyanin content was determined in the 1/6 inoculated groups. The phycocyanin content in the experimental group was found in 22.49%, and the purity rate was 2.24. In control groups, 3.73 purity and 28.62% phycocyanin were determined in the Schlösser medium. While 48.42% protein was detected in the geothermal water group, 61.64% was obtained with the Schlösser medium.

“…However, the extra additon of these substances in 1 L culture medium brought extra cost (~$0.03) that was calculated through multipling the additional quantities of subtansces (NaCl, BS and BT) by their commerical prices. In terms of the market price of food-grade phycocyanin ($0.5 g -1 ) (Güroy et al, 2017), the extra production of phycocyanin per liter (0.13 g) valued approximately $0.07, which exceeded the input cost ($0.03). Therefore, it would be cost-effective and economically feasible for the phycocyanin production after optimizaiton.…”

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.

“…Pan-utai & Iamtham (2019) reported varying extraction yields in Arthrospira platensis and purity values depending on the method of drying, and freezedrying is the most suitable method to maintain cell composition. In the literature, freeze-drying method is recommended to preserve the heat-sensitive content of cells without damaging the cell wall (Güroy et al 2017;Tavanandi & Raghavarao, 2019).…”

Phycocyanin is a precious, natural, blue coloured pigment-protein complex that has commercial value and wide application in cosmetics, food, and pharmaceutical industries.In the present study, we performed various cell disruption methods (ultrasonication, homogenization, freeze/thaw and CaCl2 extraction) for phycocyanin extraction from different forms of biomass of a thermophilic Pseudanabaena sp. that has a high potential to produce high-quality phycocyanin. Using potassium phosphate buffer and ultrasonic bath method, we achieved the highest phycocyanin yield (345 mgPC.g -biomass ) from freezedried biomass and we obtained increased yield as the duration of application increases. Phycocyanin yields were calculated as 345 mgPC.g -biomass , 255 mgPC.g -biomass and 220 mgPC.g -biomass for 5, 10 and 15 min, respectively. In this study, cell disruption methods have determined significantly more effective on freeze-dried biomass rather than frozen biomass. Phycocyanin content of freeze-dried biomass was analysed after six months of storage and dramatic decrement was observed in the phycocyanin content of the cells.
