Microalgae are microscopic organisms capable of converring solar energy into biomass vith an efficiency of 2-5 times greater than the upper foors. Also, light intensity plays an important role on the photosynthetic capacity, cell desity and lipids production. The ain ofthe study was to determine the effect oflight intensity on the growth rate, biomass production and accumulation oftotal lipids from microalgae Amazon (Ankisrodesmus sp. Chlorella sp. Scenedesmus quadricauda and Scenedesmus sp.). The microalgae ere cultured in triplicate in the medium CHU1 O under three conditions of light intensity and a control group. Cultures were tested for seven days. Daily cell count was done by microscopy using a Neubauer. Microalgal biomass was obtained by centrifugation and the total lipid content was determined gravimetrically. The results ofthe highest growth rate was obtained by Scenedesmus sp. (0.55 day-1) when grown with light intensity of 73 E.m2.s-1, addition Scenedesmussp. showed high biomass production of 175.40 mg / L and increased total lipid (22%); while Ankistrdesmus sp. Chlorella sp, and Scenedesmus quadricauda biomass production shoved 102 mg/L, 120 mg/L and 110 mg/L respectively in light intensity of 121 E.m2.s'. However, no significant differences between cultivated light intensities (p> 0.05). I conclusion, Senedesmus sp, obtained a biomass production, lipid content and optimal growth rate when grown with a light intensity of.
