Effects of photobioreactors design and operating conditions on Stichococcus bacillaris biomass and biodiesel production

Indoor cultures of Stichococcus bacillaris were carried out to investigate the effect of pH, CO2, and hydrodynamics on biomass and biodiesel productivity in a 0.6 L vertical bubble column (VBC) and a 1.7 L inclined bubble column (IBC) photobioreactor. The temperature and the irradiance level were set at 23 °C and 300 μE/(m2 s), respectively. The pH of the liquid culture was in the range 3.0–8.5. The CO2 concentration in the gas phase was...
