Efecto de la radiacion ultravioleta B en la produccion de polifenoles en la microalga marina Chlorella sp.

Abstract: Efecto de la radiación ultravioleta B en la producción de polifenoles en la microalga marina Chlorella sp. , generados como mecanismos de defensa frente a factores de estrés (radiación UV, temperatura, herbívora). El objetivo de este trabajo es evaluar la estrategia de adaptación al efecto de la radiación ultravioleta B (RUV-B, 280-315 nm) en la microalga marina Chlorella sp. mediante la producción de polifenoles y capacidad antioxidante total. Se expusieron cultivos de Chlorella sp. fueron expuestos a radiaci… Show more

“…Fucus vesiculosus, Ascophyllum nodosum and Eisenia bicyclis are one of the brown algae that have important polyphenol content (Łęska, Messyasz, Schroeder, 2018). The marked interest of these compounds is focused on the protective effect they have against UVR, although they also have other biological activities that benefit the skin such as antimicrobial, antioxidant, anti-aging, anti-cancer and anti-inflammatory (Ariede et al, 2017;Berthon et al, 2017;Copia et al, 2012;Le Lann et al, 2016;Łęska, Messyasz, Schroeder, 2018;Senevirathne, Kim, 2013;Wijesekara et al, 2011). The antioxidant property has been strongly correlated with the number of hydroxyl groups in the molecule (Łęska, Messyasz, Schroeder, 2018).…”

“…The antioxidant property has been strongly correlated with the number of hydroxyl groups in the molecule (Łęska, Messyasz, Schroeder, 2018). The mechanism of action of these molecules is as antioxidants is by the inactivation of reactive oxygen species and prevention of radical species formation (Copia et al, 2012;Łęska, Messyasz, Schroeder, 2018).…”

“…The steps to reach the “microalgal antioxidant illuminated life” are defined below:Deeply investigate the content and diversity of the least known families of microalgal bioactive molecules. Phenolics, flavonoids, and vitamins (A, B, C, D, and E) have been scarcely documented in microalgae [16,17,18,19,20,23,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77]. Compared to these families, microalgal sterols have been more documented thanks to the pioneering works of Volkman [16,63].…”

“…La producción de los compuestos fenólicos ha sido relacionada al efecto de la iluminación, siendo afectada tanto por exceso de la misma como por la radiación ultravioleta (UV). Según Copia et al (2012) la radiación UV produce, como una defensa antioxidante, un incremento en la producción de los compuestos fenólicos en Chlorella sp. Los resultados de Abdala-Díaz et al (2014) sugieren que el aumento de compuestos fenólicos observados en Cystoseira tamariscifolia (Hudson, 1950) estaría asociado a su exposición a alta iluminación y a radiación UV.…”
