Abstract:
The Photoautotrophic cultivation of Synechococcus sp. PCC 7002 in a 15 L-airlift photobioreactor was carried out. The changes of light intensity with cell density and optical length in the cultivation system were investigated. Based on experimental results, the light attenuation could be described by I = I0exp [-(-0.0239 + 0.0777 OD750).L]. The effects of the variations of light intensity, CO2 concentration in gas inlet and culture temperature on the growth of cells during the cultivation process have also been studied. The optimized condition was determined and a high dry cell density of 3.4 g/L was obtained. The volumetric productivity reached 0.57 g/(L.d) under the optimized condition.
