Obtención de ácidos grasos a partir de biomasa microalgal cultivada bajo diferentes condiciones de iluminación

It is considered that microalgae fatty acids have the potential to be used as raw material for the production of biofuels such as biodiesel or food supplements. The experimental treatment consisted in the exposure of the microalgae to different light color and photoperiod. For each treatment, microalgae Chlorella sp was cultivated from a 0.5 ml inoculum and escalated to 5 liters; the growth speed of the microalgae was determined, and the composition of fatty acids of one of the treatments was established. The treatment of red light under a photoperiod of twelve hours of light and twelve of dark showed the highest growth rate of 2.339 cells/day; the fatty acids obtained showed an important quantity of oleic acid, indicating a strong potential of the microalgae biomass for its use in alimentary industry.
