With the decrease of oil reserves and pollution caused by the increase of atmospheric CO, (1), it is important to seek an altemative energy supply and CO emission reduction, one ofthese it's microalgae oil use, because its higher nutritional element is carbon, which is converted into biomass , favoring the production oftriglyceride content(2). Varying under stressful conditions (salinity, CO concentration and nitrogen deficiency) (3). Therefore, this research was conducted to evaluate the effect of different CO exposure times in biomass production and total lipid accumulation in four Amazonian microalgae species. Scenedesmus sp . Scenedesmus quadricauda, Chlorella sp. and Ankistrodesmus nannoselene were cultured in triplicate using CHU culture medium, under 4, 6 and 8 minutes ofCO, exposure and a control group. With constant aeration, at 26 ° C, photoperiod of 12h: 12h light/dark and a light intensity of 100 E. m2. s-1 for seven days. Then, they were harvested by centrifugation and dried at 50 ° C for 72 hours. total lipids were extracted of 50 mg of dry biomass with chlorofonn : Methanol (2: l) and the content was determined gravimetrically It was detennined that the highest rate of growth was with Chlorella sp (0.18 Dia-1) in the control group. However, Scenedesmus sp. had the highest biomass production at 8 minutes of exposure (901.63mg / L), significant differences between the four species were found (F = 13.81, df= 11, p = 0.05). Concluding that the exposure time to CO induced significantly the production of microalgal biomass. As well, these treatments induced total lipid accumulation in the four species but not significantly.
