英文摘要: In this work, performances of hollow fiber membrane-sparger (MS-PBR) and contactor (MC-PBR) photobioreactors on the growth and CO2 biofixation of Synechococcus elongatus for various CO2 contents, including 0.04% (ambient air), 5% and 10% in batch and semi-continuous cultivations, were investigated. The same numbers of hydrophobic poly propylene membranes via thermally induced phase separation method were incorporated in both MS-PBR and MC-PBR modules. BG11 medium with initial pH of 8.2 and continuous illumination of 3000 lx at ambient temperature of 27 °C were kept constant for both modules and cultivation modes. The impact of recirculation flow rates of liquid medium on the biomass growth and CO2 biofixation in semi-continuous cultivation mode for both modules were also investigated. The maximum CO2 biofixations of 2.43 and 2.08 g L d-1 were obtained for MS-PBR and MC-PBR at CO2 content of 5 and 10%, respectively. It can be concluded that MS-PBR is suitable for high cell density cultivation at low CO2 content in equal gas flow rate due to the maximum growth rate under 5% CO2 condition. Cell growth was inhibited in the presence of 10% CO2 inlet feed gas. On the other hand, MC-PBR showed better growth at higher CO2 contents (10% CO2). © 2016 Elsevier Ltd. Citation statistics:
