Abstract
We evaluated the kinetic culture characteristics of the microalgae Cyanobium sp. grown in vertical tubular photobioreactor in semicontinuous mode. Cultivation was carried out in vertical tubular photobioreactor for 2 L, in 57 d, at 30 °C, 3200 Lux, and 12 h light/dark photoperiod. The maximum specific growth rate was found as 0.127 dâ1, when the culture had blend concentration of 1.0 g Lâ1, renewal rate of 50%, and sodium bicarbonate concentration of 1.0 g Lâ1. The maximum values of productivity (0.071 g Lâ1 dâ1) and number of cycles (10) were observed in blend concentration of 1.0 g Lâ1, renewal rate of 30%, and bicarbonate concentration of 1.0 g Lâ1. The results showed the potential of semicontinuous cultivation of Cyanobium sp. in closed tubular bioreactor, combining factors such as blend concentration, renewal rate, and sodium bicarbonate concentration.
