Abstract
The influence of aeration time and concentration of sodium silicate (Na2SiO3) in the cultivation of the microalgae Nannochloropsis oculata was studied. Aeration pumps were turned off for 2, 4, and 6 h, while cells were exposed to Na2SiO3 at concentrations of 40.0, 50.0, and 60.0 g.L− 1 under constant artificial lighting. It was observed that cell growth and bio-oil production were dependent on Na2SiO3 concentration but not on aeration time. Cellular density of 132.104 cel. mL− 1, and about 15% of oil yield were obtained.
