“…In Spirulina (A. platensis) production, the interaction of different factors, including nutrients and light intensity and salt concentration affect the photosynthetic efficiency, growth, productivity and the bioactive compounds of the blue-green algae. In a study the process of photosynthesis in the spirulina was found to be negatively affected by the increase in a concentration of salt from 2.5 to 5 and 10 % (V/V), while a decrease in growth and productivity of the blue-green algae was simultaneously observed ( Markou et al, 2021 ). On the other hand, other research findings revealed that the amount of phenolic compound in the Spirulina was increased eight times through the application of light intensity treatment, while at the same time an increment was seen in on the important nutrients, such as protein, carotenoids, carbohydrates, phycocyanin and antioxidant activities (Aysun et al, 2012).…”

“…For example, the biomass with high phycocyanin content can be specially used for the development of natural food colors or other phycocyanin products, while the one containing high carbohydrates content has potential as a source for biofuel generation or active polysaccharides production. However, even though it was associated with genetic characteristics of algal strains, the substances contained in the Arthrospira biomass were influenced by factors such as amounts of nutrients (fertilizers), temperature, and light intensity [ 13 , 15 , 20 , 34 , 35 ].…”

“…The maximum biomass productivity occurred on day 25, with 21.97 g m −2 d −1 , but the average biomass productivity (3.96 g m −2 d −1 ) was much lower than previously reported [ 16 , 38 ]. The medium components and environmental factors largely affect the growth [ 13 , 15 , 20 , 34 , 35 ]. The growth, shown as biomass production and productivity in our study, was significantly lower than the results from those studies mentioned above, which was mainly attributed to the following reasons.…”

Arthrospira platensis, a well-known cyanobacterium, is widely applied not only in human and animal nutrition but also in cosmetics for its high amounts of active products. The biochemical composition plays a key role in the application performance of the Arthrospira biomass. The present study aimed to evaluate the growth and biochemical composition characteristics of A. platensis, cultured with a nitrogen-free and seawater-supplemented medium in an outdoor raceway pond in winter. The results showed that the biomass yield could achieve 222.42 g m−2, and the carbohydrate content increased by 247% at the end of the culture period (26 d), compared with that of the starter culture. The daily and annual areal productivities were 3.96 g m−2 d−1 and 14.44 ton ha−1 yr−1 for biomass and 2.88 g m−2 d−1 and 10.53 ton ha−1 yr−1 for carbohydrates, respectively. On the contrary, a profound reduction was observed in protein, lipid, and pigment contents. Glucose, the main monosaccharide in the A. platensis biomass, increased from 77.81% to 93.75% of total monosaccharides. Based on these results, large-scale production of carbohydrate-rich A. platensis biomass was achieved via a low-cost culture, involving simultaneous nitrogen deficiency and supplementary seawater in winter.

“…Microalgae is in high demand in many biotechnology sectors such as bioremediation, biofuels, biofertilizers (Kosamia et al, 2020;Markou et al, 2021), cosmetics, biomedicals (Mesquita et al, 2017;Mellou et al, 2019;Wen et al, 2020), aquaculture (Shah et al, 2018) and animal and human nutrition (Molino et al, 2018) because of the biological and commercial value of its products. In this respect, Spirulina platensis is one of the most promising microalgae (Lupatini et al, 2017).…”

The prospects for using Moringa oleifera leaves extract (MLE) supplemented with different concentrations of kanwa or sodium bicarbonate (NaHCO 3 ) as a low-cost alternative growth medium of Spirulina platensis were evaluated in a small-scale outdoor cultivation system. The present study was aimed to evaluate the potential of MLE growth medium enriched with different concentrations (4 or 8 g L -1) of kanwa and NaHCO 3 on growth, chlorophyll content, biochemical characteristics, antioxidant compounds and some physico-chemical factors. Jourdan's standard medium was taken as control. The results showed that the growth parameters such as cell population, biomass dry weight, cell productivity and specific growth rate were positively affected in MLE cultivation medium enriched with kanwa or NaHCO 3 at different concentration levels. The addition of urea, kanwa or NaHCO 3 in MLE cultivation medium at different concentration levels increased significantly (p< 0.05) the protein content, the peroxidase and polyphenol oxidase activity, the conductivity, pH, total dissolved solids and salinity from 20 to 25 days of cultivation whereas a decrease in carbohydrate and phenol content was recorded during all the period of the experimentation. The highest values of growth parameters were notably in MLE medium supplemented with urea and kanwa at 8 g L -1. The MLE medium enriched with urea and kanwa at 8 g L -1 was shown to be an appropriate growth medium that can be used as a lowcost alternative growth medium for commercial cultivation of S. platensis.
