Seaweeds, as biofilters that remediate seawater eutrophication, have been widely applied in integrated cultivations for both ecological and economic benefits. Although Grateloupia turuturu (Rhodophyta) is considered as a qualified species in integrated maricultivation, its growth and biochemical performance under different nitrogen conditions are still unknown. Here, we cultured G. turuturu under two nitrogen sources (nitrate and ammonium) at six concentrations (0, 25, 50, 100, 200, and 400 µM) to investigate its growth and nitrogenous compounds (total and inorganic nitrogen, soluble protein, amino acids, and pigments) as well as the allocation pattern of nitrogen storage pools. Our results showed that G. turuturu was well acclimated to high concentrations of both nitrogen sources, and algal age played an important role in the preference of nitrogen sources. Most of the biochemical compositions in G. turuturu increased significantly with the increased concentrations of nitrogen, except for the protein and nitrate contents. Protein and residual organic nitrogen (RON, mainly amino acids) were found to be the two main nitrogen storage pools in G. turuturu. Our study revealed that G. turuturu can produce more profitable compositions at high nitrogen concentrations, making it a profitably promising biofilter to remediate eutrophication.

“…The fit between dry weight and optical density (Equation 2) was obtained at 680 nm (OD 680 ) with an R 2 = 0.9990. This method which uses dry weight is more important than the method using wet mass (Moraes et al, 2018). Calculation results of total expected biomass can be measured in seconds.…”

Water compatibility of M’sila region (South- East Algeria) for cultivation of Spirulina & evaluation of methods of extraction of Phycocyanin and investigation of stability by β-Cyclodextrin

Spirulina (Arthrospira platensis) is a microalga that has existed for more than three billion years. It belongs to the family of cyanobacteria. It is extraordinary, rich in nutrients such as proteins, carbohydrates, lipids, vitamins, and minerals. In addition, Spirulina is rich in phycocyanin, a blue protein pigment. It can be used as a dye in food, pharmacology, and cosmetics. Our work focused first on the compatibility of the waters of M’sila region (southeast Algeria) for the cultivation of Arthrospira platensis. Then, we evaluated several methods of extracting phycocyanin to be able to determine the optimal method in terms of yield. We have succeeded in developing a new extraction method coupled with maceration in a glycerol-water mixture with a molar ratio (8/2) assisted by ultrasound with a yield of 52.93 mg/g. The excellent results obtained may be due to the salinity of the waters of the region, to the used nutrient culture medium and/or the climate change of the region. We have formed an inclusion complex between phycocyanin and β-Cyclodextrin to keep it and make it more stable. The encouraging results allow Algeria to gain a foothold on the world market as a producer of blue goldSpirulina (Arthrospira platensis) is a microalga that has existed for more than three billion years.

“…The carbohydrate content in S. platensis biomass is influenced by nitrogen concentration (Menegol et al, 2017). At low nitrogen concentrations in cultivation media, lipid and carbohydrate biosynthesis increases (Fan et al, 2012;Ho et al, 2012;Wang et al, 2014;Moraes et al, 2018) while protein synthesis decreases (Zhu et al, 2014). Markou et al (2012) reported that the phosphorus concentration of 10 mg/L in the form of K 2 HPO 4 in cultivation media could increase the carbohydrate content in S. platensis biomass.…”

The major costs of cultivating S. platensis are for media and labor. The aim of this study was to explore the use of goat manure as culture medium for S.platensis. A complete randomized block design was used in this study with 5 treatments of goat manure concentration, each of which was repeated 5 times. The results of the study showed that the growth of S.platensis at 25 g/L concentration of goat manure was significantly (P<0.05) lower than 50, 75, 100 g/L and Zarrouk media. S.plantesis productivity at a concentration of 25 g/L goat manure (0.128±0.011 g/L/day) was significant (P<0.05) lower than 50 (0.153±0.012 g/L/day), 75 (0.158±0.014 g/L/day), 100 g/L (0.153±0.009 g/L/day) and Zarrouk media (0.164±0.016 g/L/day). Protein content in S. platensis at 50 (59.03±4.31%), 75 (62.56±6.04%) and 100 g/L (61.22±4.54%) goat manure and Zarrouk (63.21±5.97%) media were significantly (P<0.05) higher than 25 g/L (47.35±5.16%). Lipid content in S. platensis at Zarrouk media (5.28±0.38%), 50 g/L (5.31±1.27%), 75 g/L (5.37±1.25%) and 100 g/L (5.42±1.35%) goat manure were significantly (P<0.05) lower than 25 g/L (7.86±1.16%). Carbohydrate content in S. platensis at Zarrouk (22.58±2.38%), 50 g/L (21.67±2.25%), 75 g/L (22.43±2.14%) and 100 g/L (22.67±2.38%) goat manure were significantly (P<0.05) lower than 25 g/L (27.69±1.78%). Chlorophyll content in S. platensis at Zarrouk and goat manure with 50, 75 and 100 g/L concentration were significantly (P<0.05) higher than 25 g/L (1.36±0.15%). We conclude that the concentration of goat manure 75 g/L in S.platensis cultivation media was the optimum concentration and has the potential to replace inorganic media.
