Production of Chlorella Vulgaris Using Urban Wastewater: Assessment of the Nutrient Recovery Capacity of the Biomass and Its Plant Biostimulant Effects

The microalga Chlorella vulgaris UAL-1 was produced using urban wastewater that was either left untreated or sterilised. The biomass productivity achieved when using the untreated wastewater was comparable to that of the control, which was freshwater supplemented with synthetic chemicals (0.58 g·L−1·day−1). The microalga C. vulgaris UAL-1 was able to recover up to 93.8, 73.1, 80.5, and 85.2
