Comparación de parámetros proximales entre aislados comerciales y Arthrospira platensis Gomont, especie cultivada en condiciones controladas en Paraguay
At present, microalgae have become the object of great interest, since they are a source of important natural substances and produce biomaterials that present various industrial applications. The proximal parameters of three isolated species of the genus Arthrospira of different geographical origins were analyzed, out of which two were of Chilean and Argentine origin; the third isolate was obtained from the cultivation under controlled conditions of the Arthrospira platensis native of Paraguay, in a batch-type photobioreactor with Zarrouk medium under 24-hour light conditions, 0.45 vvm and luminous Intensity of 12,500 lm for 75 days, which generated a yield of 5.82 grams of biomass per liter of culture. Determinations made to evaluate the proximal composition of the three isolated were moisture, ash, proteins and total fats. For the strain of Arthrospira platensis native to Paraguay, the value of the percentage of protein obtained was about 67.40%, total fats 5.69%, humidity 20.02% and ash 9.11%. These results of the parameters analyzed suggests that this microalga could be used as a nutritional supplement.
