    Efecto de las Bajas Concentraciones de Nitratos y Fosfatos sobre la Acumulación de Astaxantina en Haematococcus pluvialis UTEX 2505
    (Centro de Informacion Tecnologica, 2019-01-01) Miranda A.M.; Ossa E.A.; Vargas G.J.; Sáez A.A.; Universidad EAFIT. Departamento de Ciencias; Ciencias Biológicas y Bioprocesos (CIBIOP)
    In this study, the effect of the concentration of nitrogen and phosphorus on the accumulation of Astaxanthin in Haematococcus pluvialis UTEX 2505 was evaluated using a factorial 3 2 design. The dependent variables were cell growth, Astaxanthin production, lipid profile and Young's modulus of the cell membrane. It was found that cellular productivity increases when nitrogen levels were high, in contrast to low concentrations of nitrogen and phosphorus that showed a positive effect on Astaxanthin production. The stress generated by the source of nutrients decreases the rigidity of the cellular wall in the microalgae. As a conclusion, to obtain higher concentrations of Astaxanthin it is necessary to limit the nitrogen and phosphorus levels. © 2019 Centro de Informacion Tecnologica. All Rights Reserved.
