Lipid and carbohydrate profile of a microalga isolated from wastewater

Native species of Asterarcys quadricellulare was isolated from wastewater from the International Centre for Reference and Water Reuse at the São Paulo University campus. Microalga was cultivated at 24.2 ± 1.2 ºC under mixotrophic conditions in Bold Basal medium supplemented with 0.1 g/L glucose, under 12 h:12 h light:dark photoperiod of artificial light, in 2 L photobioreactors. A. quadricellulare achieved 0.463-0.567 g/L (dw) concentration, with 20.0 % lipid and 36.6 % carbohydrate. Yields of 0.0198 g oil and 0.0362 g sugar /L-1.day-1 show this microalga potential for biofuels production and wastewater treatment.
