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 CO2and harvesting the biomass it the stationary phase of growth.

Biodiésel a partir de microalgas, un proceso en exploración

Microalgae biomass has been described by several authors as the raw material with the greatest potential to meet the goals of replacing petroleum diesel by biodiesel while not competing with arable land suitable for food production. Research groups in different countries are seeking the most appropriate production model for productivity, economic viability and environmental sustainability. This review focused on recent advances and challenges of technology for the production of biodiesel from microalgae, including the procedures used to obtain biomass. O biodiesel pode ser usado puro ou em misturas com o diesel em motores ciclo diesel, sendo, em alguns aspectos, comparativamente menos poluente que o diesel. As microalgas apresentam, portanto, potencial produtivo destacado.
