碩士 / 大葉大學 / 環境工程學系碩士班 / 97 / Continuous cultivations of Tetraselmis chui were conducted in a light/dark dual-tank photobioreactor using modified Walne medium with sodium bicarbonate as the carbon source. The effects of sodium bicarbonate concentration and light intensity on growth of Tetraselmis chui were investigated in this study.
Effects of sodium bicarbonate concentration in feed on growth of Tetraselmis chui were conducted with five concentrations of 0.5, 1.0, 1.5, 2.0, and 3.5 g/L. According to the results, biomass concentration increases with the increase in sodium bicarbonate concentration. Saturation for biomass concentration was occurred at higher concentration of sodium bicarbonate. However, there is no significant effect on growth rate of Tetraselmis chui with the change in sodium bicarbonate concentration. Culture pH decreases with the increase in concentration of sodium bicarbonate due to the buffer capacity of sodium bicarbonate. Effects of light intensity on growth of Tetraselmis chui were conducted with three light intensity of 4000, 4800 and 5500 lux. The results show that the higher intensity, the higher growth rate is. However, biomass concentration did not change with these three light intensities. It also observed that saturation of grow occurred at higher light intensity.
