摘要：

Photosynthetic CO2 fixation was investigated in a cylindrical shaped helical tubular photobioreactor incorporating the filamentous cyanobacterium Syirulina platensis. A laboratory scale photobioreactor was constructed with a 0.25 m(2) basal area in a cylindrical shape(0.9 m high x 0.57 m diameter). The photostage comprised transparent polyvinyl chloride tubing (60 m in length and 1.6 cm internal diameter with 0.3 cm wall thickness, total volume=12.1 litre). The inner surface of the photostage (1.32 m(2)) was illuminated with cool white fluorescent lamps; the photosynthetically active radiation(PAR, 400-700 nm) energy input into the bioreactor was 2920 kJ per day. The operation of the air-lift photobioreactor with CO2 enriched air(4%) at a flow rate of 0.3 litre min(-1) showed a maximum daily photosynthetic efficiency of 5.45 % (PAR) under batch culture conditions. This corresponded to a production I ate of 30.2 g dry weight (14.6 gC) m(-2) (basal area) day(-1).
