Las microalgas son consideradas alimentos funcionales, capaces no sólo de elevar el contenido nutricional de los alimentos tradicionales, sino también de afectar positivamente la salud de animales y humanos, debido a que contienen cantidades apreciables de proteínas, vitaminas y ácidos grasos poliinsaturados. Algunas microalgas incluso tienen un contenido aminoacídico superior al presentado por alimentos convencionales; tal es el caso de Scenedesmus sp que posee niveles de lisina superiores al patrón de la Food and Agriculture Organization of the United Nations (FAO), y niveles de proteína entre 25 y 35 % lo que la hace una atractiva fuente de proteína. Por lo tanto, en este trabajo se busca el medio de cultivo donde se pueda alcanzar la mayor producción de biomasa y proteína de la microalga verde Scenedesmus sp, evaluando los medios de cultivo Estándar 1, Estándar 2 y Algal, empleando, NaHCO3 como fuente de carbono. El medio Estándar 2 presenta la mayor producción de biomasa (0.41 g/ L) y el medio Algal, el más alto porcentaje de proteína por materia seca (35.18%). Adicionalmente se estudia el polimorfismo que presenta la microalga en cada medio de cultivo, y se hacen evidentes cambios morfológicos, incluso entre colonias con el mismo número de células. Esta microalga tiene aplicación potencial en la industria de alimentos balanceados para animales.Microalgae are considered as functional food capable not only of raise nutritional content but also of affect positively the animal's health and human's containing important amounts of proteins, vitamins, and polyunsatured fatty acids. Some Microalgae have even higher amino acid content than conventional food; Scenedesmus sp has a lysine level higher than the required for the Food and Agriculture Organization of the United Nations (FAO) and proteins levels between 25 and 35%, becoming a rich protein source. In this study, biomass and protein production of Green microalgae Scenedesmus sp, in different growth mediums, Standard 1, Standard 2 and Algal with NaHCO3 as carbon source, , were evaluated, . Among mediums:. Standard 2 medium had presented the higher biomass production (0.41 g/L) and the Algal medium the higher protein percentage measured by dry weight (35.18%). also, polymorphism presented by the microalgae in each medium was studied; which show morphological changes even among colonies with same cells number. This microalgae has a potential application in animal food industry.
