The use of microalgae lipids or the whole biomass for generation of biodiesel, methane, hydrogen ... more The use of microalgae lipids or the whole biomass for generation of biodiesel, methane, hydrogen and other valuable fuels is very attractive. Among the many requirements for microalgae growth is a specific culture media, which provides the cells of macro and micronutrients. These are specific for every strain and represent a cost for the biomass and/or the specific target production. Human urine has a potential for different activities, such as greenhouse culturing of microalgae, zooplankton and vegetables. The aim of this work was to demonstrate that three strains of microalgae are capable of growing in human urine dilutions, and they can produce lipids in amounts similar to those produced when growing in a commercial media (BBM). The three evaluated strains can be cultured in media containing 1:50 to 1:200 dilutions, giving biomass concentration higher than those found when using BBM media. Regarding the lipids production, values were quite near than those obtained when growing the microalgae in BBM media. Nevertheless, the product of the maximum absorbency x lipid concentration values are very similar for Chlorella vulgaris and Scenedemus sp growing in urine to those observed when growing in BBM media. This finding has tremendous implications over the biodiesel based on microalgae process. Culture media could be formulated almost exclusively with urine. Next step of this project will be the optimization of media containing human urine and small amounts of some essential metals such as Cu, Fe, Mg, Zn etc.
