The third phase occurred up to 378 °C with 32% of weight loss (Hussein et al. Live Arthrospira platensis - Spirulina Food for Aquarium Animals and Grow at Home kits - 8 oz (230ml) Arthrospira (Spirulina) platensis is a cyanobacteria that is incredibly high in protein, lipids and other nutrients. In this work, an experimental design methodology was used to investigate the combined effect of nitrogen concentration and PFD on the biomass concentration and EPS content from the cultivation of A. platensis. 2,  3, according to the values presented in Table 2: It is noteworthy that the lack of fit values for both biomass and EPS production were significant (p < 0.05). Phycocyanobilin (PCB) is an important linear tetrapyrrolic molecule for food as well as pharmaceutical industry. Antenna Technologie, Genève. High-irradiance grown cells showed the greatest photosynthetic capacity even though they had a. Thesis (Ph. Finally, viscosity changes under steady-flow regime were investigated as a function of shear rate, from 10 to 102 s−1. https://doi.org/10.1016/j.biortech.2009.02.006, Mishra A, Kavita K, Jha B (2011) Characterization of extracellular polymeric substances produced by micro-algae Dunaliella salina. statement and The purification steps consisted of extraction, hydrophobic interaction chromatography and ion exchange chromatography. 2011). The relative fragility of microalgae requires choosing a suitable pumping system. PubMed  A widely used technique for cell harvesting is crossflow microfiltration. The broad bands observed around 3400 cm−1 are attributed to O–H and N–H stretching. Bioresour Technol 146:732–735. Modified Zarrouk's culture medium was used . The second highest EPS content (100 mg g−1) was obtained under conditions of the highest values of NaNO3 (2 g L−1) and PFD (1000 μE m−2 s−1). However, the intracellular events that lead to EPS production are still being deciphered. J Biotechnol 102:143–152. In the first stage, 15% weight was lost up to 155 °C. In this case, the final biomass concentration was observed to increase, reaching 1.2 g L−1 with a NaNO3 concentration of 74.3 mg L−1, but then decreased at values higher than 100 mg L−1. This bacterium is non-nitrogen-fixing photoautotroph .

These pigments work in conjunction with chlorophyll a to optimize light harvesting for photosynthesis, particularly under light limiting conditions. 1951). Their rheological behaviors were quite similar to that previously observed for other polysaccharides, such as gum algaroba, a galactomannan extracted from Prosopis juliflora (Azero and Andrade 2006). The present study aimed to investigate the growth of Arthrospira, Arthrospira (Spirulina) platensis is one of the most cultivated commercial microalgae. Terms and Conditions, It is also an extremophile for pH, it does very well at pH ranges up to 10.5. The values of the final biomass concentration and the EPS yield are given in Table 1. The phylum of cyanobacteria comprises a group of diverse prokaryotes. PCC 8005 studied by integrating transcriptomic and proteomic approaches. Cite this article. The lowest PFD (200 μE m−2 s−1) and NaNO3 concentration (0.5 g L−1) resulted in the highest EPS yield. This chapter focuses on the phycobilisome characteristics, their relationship to the photosystems in the thylakoid membrane, and major problems to be addressed in future investigations. Nevertheless, it is possible to choose a condition in which the EPS content as well as biomass concentration could be produced at reasonable values. Simultaneously, eight market products were also classified into the cluster with high growth yield. Having removed unbound proteins and cellular debris, the bed was allowed Influence de la teneur en lower chlorophyll and phycobiliprotein content. 2018). It is likely that the nitrogen-reduced conditions in this work did not compromise the biomass production and were high enough to sustain the cell growth. Aqueous solutions of EPS 01 (0.25 gL−1 NaNO3 and 200 μE m−2 s−1) and EPS 09 (2 gL−1 NaNO3 and 1000 μE m−2 s−1) were prepared at 5 g L−1 and 10 g L−1, and their rheological properties were investigated. The difference became more evident on day 23, where After 12 h at 4 °C, the product was filtered and completely dried in an oven at 60 °C. The analysis of photochemistry of the atmospheric constituents is made possible by measurements of solar radiation with space vehicles and the now excellent data on uv absorption. https://doi.org/10.1016/j.biortech.2017.12.068, Markou G, Angelidaki I, Georgakakis D (2012) Microalgae carbohydrates: an overview of the factors influencing carbohydrates production and of main bioconversion technologies for production of biofuels.

Jourdan J.P., (1996) « Sugar as a source of carbon for spirulina (Arthrospira platensis) culture, 1 shows the growth of Arthrospira platensis in the three tested culture media. On the contrary, electronic microscope observation revealed that, during concentration using an eccentric rotor pump or a peristaltic pump, microalgae were not damaged. The thermal degradation of EPS from microalgae and cyanobacterium was recently reported. Temperature of the culture during daylight exerted the predominant effect on productivity and elevating the temperature resulted in a significant rise in productivity even in summer. In particular, Arthrospira maxima is one of the most efficient hydrogen-producing cyanobacterium 4,5, and Arthrospira platensis also produces large amounts of hydrogen 6. To eliminate residual salt, the samples were resolubilized in distilled water and then dialyzed against water under constant stirring at room temperature for 24 h. The final product was recovered by adding 95% ethyl alcohol and lyophilized. https://doi.org/10.1016/j.biortech.2005.09.008, Pereira S, Zille A, Micheletti E, Moradas-Ferraira P, De Philippis R, Tamagnini P (2009) Complexity of cyanobacterial exopolysaccharides: composition, structures, inducing factors and putative genes involved in their biosynthesis and assembly. However, only a few studies have been conducted with the objective to enhance the EPS yield from species of cyanobacteria. Charpy L., (2008). Our main objective is to deepen our knowledge on the culture of this μalguae and phycocyanin extraction in order to study the feasibility of the creation of a Spirulina farm in Guelma, a region with climatic and ecological contexts favor this project. London: Bristol, PA: Taylor & Francis. (2009a) carried out a study evaluating the effect of different temperatures and PFD on the final biomass and EPS concentrations by A. platensis, and described a possible correlation between the two responses. Cluster analysis showed the separation of all the strains into two main clusters. For single attached cells, the lower ice nucleation temperature, corresponding to increased incidence of IIF, resulted in decreased post-thaw cell recovery. It is commonly found all around the world making it one of the rare endemic strains of the Earth. 2012; Dejsungkranont et al. 8 8 { }A^{ 2} \, + \, 2 4. https://doi.org/10.1007/s10452-019-09699-z, Carvalho AP, Silva SO, Baptista JM, Malcata FX (2011) Light requirements in microalgal photobioreactors: an overview of biophotonic aspects. 2018) have already been reported for EPS of cyanobacteria. After a period of 10 min, an oscillatory frequency scan was performed, from 10−1 to 7 × 102 rad s−1 (with a deformation value of 10%), within the region of linear viscoelasticity. 4.2.1 Productivity analysis of Arthrospira platensis culture using recycled culture medium ..... 59 4.2.2 Elemental analysis of fresh and recycled culture medium..... 65 4.3 Assay 3: Analysis of Arthrospira platensis growth in alternative culture medium to be ignored. Cyanobacteria produce extracellular polymeric substances (EPS), which have a protective function in biofilm formation, a mechanical barrier against desiccation (Decho and Gutierrez 2017), and which also aids in the absorption of heavy metals (Goo et al. The 16S rRNA genes appeared too conserved for discrimination of the strains by amplified ribosomal DNA restriction analysis, and thus the internally transcribed spacer was selected as molecular taxonomic marker. 2007). Spirulina platensis was cultivated in laboratory under controlled conditions in four different culture media, BG-11, modified BG-11, Zarrouk's (ZM) and synthetic human urine (SHU). IO9201 isolated from Caribbean waters. and the purity of recovered phycocyanins was confirmed by absorption and emission spectroscopy.

Moreover, yield of PCB in the cleavage process is found to be proportional to the initial concentration of phycobiliproteins. Phycocyanobilin was distributedoutside in the liposomes to scavenge radicals fromAAPH and to prevent initiation of radical chainreactions. The most intense absorption of the spectrum, at 1046 cm−1, may be attributed to C–O–C, S–O and P–O–C stretching vibrations. Today these bacteria, as well as microscopic algae, supply oxygen to the atmosphere and churn out fixed nitrogen in Earth's vast oceans. In this work, cleavage of PCB from phycobiliproteins present in the extract of Arthrospira platensis by methanolysis is investigated.
