Abstract

ARIAS PENARANDA, MARTHA TRINIDAD; MARTINEZ ROLDAN, ALFREDO DE JESÚS  and  CANIZARES VILLANUEVA, ROSA OLIVIA. Biodiesel Production from Microalgae: Cultivation Parameters that Affect Lipid Production. Acta biol.Colomb. [online]. 2013, vol.18, n.1, pp.43-68. ISSN 0120-548X.

The microalgae have the capacity to mitigate CO2 emissions and to produce lipids, which are considered with potential to obtain third-generation biofuel. This review provides updated information of the influence of culture conditions on the lipids production with high productivity and profile suitable for the biodiesel production. This document presents a compilation of research conclusions over the last 13 years around the world. In the literature consulted, the authors conclude that although the behavior of microalgae at physiological stress conditions, varies between species; the nutrients limitation, especially nitrogen and phosphorus, associated with heterotrophic growth or high irradiances in phototrophy are considered the most efficient strategies to increase the lipid content in microalgae, particularly triglycerides (consisting of saturated and monounsaturated fatty acids), which are excellent for the production of biodiesel. Also, it is reported that the lipid content increase and the number of unsaturated fatty acids decrease with the addition of small amounts of CO2 and harvesting the biomass it the stationary phase of growth.

Keywords : biofuels; microalgae; lipids; fatty acids.
