Third generation biofuels from photosynthetic microorganisms
are currently presented as a promising renewable alternative to
fossil fuels. One of the weak points of this technology to be
implemented in a large scale is the supply of nutrients [1]. The use
of wastewater as nutrient source could overcome this issue,
contributing at the same time to wastewater bioremediation.
Indeed, several studies have reported the growth of microalgae
using different wastewaters as nutrient source [2]. Opposite to
traditional manure management procedures where nutrients are
lost, coupling swine slurry treatment with microalgae cultivation
would result in sustainable nutrients recycling. However under
specific circumstances, nitrogen loss by ammonia stripping and
nitrificationedenitrification processes has been previously reported
when using microalgae-bacteria consortium to treat
