Resumen:
Microalgae have been recognized as a resource of great interest worldwide,due to the ability to store useful chemical compounds and pigments of high industrial value in their biomass. They have regained their prominence in recent years when the production of liquid biofuels from food crops began to generate debates about the socio-environmental impacts. The photosynthetic microalgae have high efficiency and rapid growth rate,flexibility to grow in any liquid medium including effluents, higher productivity compared to conventional crops and without dependence on fertile land. These qualities make them apromising alternative for the global energy supply. The solar radiation is the factor that defines the maximum biomass production capacity of the different species. Northern Argentina, one of the 7 regions with the highest level of solar radiation, provides the optimal conditions for algal growth, although this advantage has not yet been sufficiently exploited. Our group has focused on performing laboratory experiments with the Scenesdesmus quadricauda, scaling its culture and identifying management guidelines. In the lab up to a 20-liter scale, a favorable growth response has been observed at room temperature, both in the cold and warm seasons, with a growth cycle of 20 days. However, itwas interesting to explore the behavior of the sp in outdoor ponds, observing whether solar radiation constituted a comparative advantage for its growth.
