| heal.abstract | In this thesis, an attempt was made to study the development of Arthrospira platensis (spirulina) culture under different lighting and salinity conditions at a controlled constant temperature and to compare crop yields. Arthrospira platensis is a prokaryotic microflora and belongs to the cyanobacteria. Its unique chemical composition, rich in protein, y-linolenic acid, vitamins, iron and more, is a catalyst for its commercial exploitation. Due to the global depletion of water resources and the increasing seawater penetration into the aquifer, the prospect of growing spirulina on a commercial scale using brackish or seawater is of particular interest. The experiment was carried out in a temperature controlled laboratory, in two zones of different light intensity, 5 klux and 15 klux, and in scaled salinity, with added NaCI Ogr/I, 10gr/l, 20gr/l and 30gr/l. The strains used are SAG 257.80 freshwater Arthrospira platensis, coming from Lake Huacachina, Peru (South America), and SAG 21.99 brakish Arthrospira platensis, coming from Namibia (Africa), supplied by Experimental Phycology and Culture Collection, University of Goettingen, Germany (SAG University). Growth rate was calculated by using, an Optical Density (OD) and Dry Weight (DW ) curve. Statistical analysis of the results showed that light intensity affects significantly the productivity and growth rate of the crop, with 15 klux being better and this result is consistent with previous studies (Vonshak A. 1197, Soletti et al. 2008, Trabelsi et al. 2009). The fluctuation of salinity, by contrast, did not give statistically significant differences in crop growth within the range studied (S = 0-30 %o). The results of the experiment show that, a spirulina strain such as Brackish SAG 21.99, could be cultivated in areas where water is unsuitable for irrigation or even using seawater. This cultivation can lead to the production of high quality protein in areas degraded and unsuitable for any type of cultivation, while saving the precious water resources of our planet. Especially for our country, with 16,000 kilometers of coastline, the prospect of the development of spirulina coastal crops could give a great boost to the regional and national economy. | en |
