Zusammenfassung:Alternative culture media have been evaluated for the cultivation of microalgae, among them are, industrial and agriculture wastewaters, that make residue recycling possible by bioconverting it into a rich, nourishing biomass that can be used as a feeding complement in aquaculture and in diverse areas. The objective of this research is to determine the iipid, fatty acid profile and carotenoid produced by the microalgae Chlorella vulgaris cultivated in a hydroponic wastewater, with different dilutions. The results showed that Iipid contents did not present significant differences. Fatty acids were predominantly 16:0, 18:0, 18:1 and 18:3n-6. For total carotenoids, the dilution of hydroponic wastewater did not stimulate the production of these pigments. From this study, it was determined that, the use of hydroponic wastewater as an alternative culture medium for the cultivation of Chlorella vulgaris generates good perspectives for Iipid, fatty acid and carotenoid production.Original Abstract: Medios de cultivo alternativos vienen siendo evaluados para el cultivo de microalgas, entre ellos, estan los afluentes industriales y agricolas, que posibilitan la reciclaje del resi duo, bioconvirtiendose en una biomasa enriquecida bajo el punto de vista nutricional, que puede ser utilizada como com plemento alimenticio, para la acuacultura y en varias otras areas de actuacion. El presente trabajo tuvo como objetivo determinar los contenidos de Iipidos, composicion de acidos grasos y carotenoides producidos por la microalga Chlorella vulgaris cultivada en solucion hidroponica residual, con dife rentes diluciones. Los resultados de los contenidos de Iipidos totales no presentaron diferencia significativa. Los acidos grasos predominantes fueron los 16:0,18:0,18:1 e 18:3n-6. Para los carotenoides totales, la diluclon de la solucion hidroponica residual no estimulo la produccion de estos pigmentos por la microalga. La utilizacion de la solucion hidroponica residual como medio de cultivo alternativo para Chlorella vulgaris genera buenas perspectivas para la produccion de Iipidos, acidos grasos y carotenoides.
