 Cyanobacterial CO 2 biofixation in batch and semi‐continuous cultivation, using hydrophobic and hydrophilic hollow fiber membrane photobioreactorsVahid Mortezaeikia, Omid Tavakoli, Reza Yegani and Mohammadali Faramarzi Greenhouse Gases: Science and Technology, 2016, vol. 6, issue 2, 218-231 Abstract: The performance of hollow fiber membrane photobioreactors (HFMPB) for the growth of Synechococcus elongatus at various CO 2 concentrations (0.04% (ambient air), 10% and 15%) and medium re‐circulation flow rates (34.4, 60 and 86.6 mL/min) was studied. Cultivation was carried out at both batch and semi‐continuous modes in HFMPBs containing neat and hydrophilized in‐house fabricated poly propylene (PP) membranes at a fixed light intensity of 3000 lux and temperature of 27-super-oC. Cyanobacterium showed better growth at 10% CO 2 at an initial pH = 8.2 using BG11 medium in both cultivation modes and modules. Maximum biomass concentration, CO 2 biofixation and specific growth rates equal with 2.1 g L-super-–1, 2.08 g L-super-–1d-super-–1 and 1.76 d-super-–1 were obtained for non‐wetted membranes, respectively. Comparing the performance of both modules showed that the impact of cultivation mode on the CO 2 biofixation rate and CO 2 removal is more influential than the impact of mass transfer resistance in membrane contactors. © 2015 Society of Chemical Industry and John Wiley & Sons, Ltd Date: 2016 Downloads: (external link) Related works: Export reference: BibTeX RIS (EndNote, ProCite, RefMan) HTML/Text Persistent link: https://EconPapers.repec.org/RePEc:wly:greenh:v:6:y:2016:i:2:p:218-231 Access Statistics for this article More articles in Greenhouse Gases: Science and Technology from Blackwell Publishing |
