CO2enriched air bubbling is commonly used in the conventional algal culture systems, but for offshore culture systems, supplyg CO2 is costly. The effect of NaHCO3 concentration on the biomass productivity of Tetraselmis sp. KCTC12432BP, was investigated. The microalgae were cultured using modified f/2-Si medium based on natural seawater in Floating Cube photobioreactors (FC-PBRs) in the Youngheung island, Incheon, Korea. The biomass productivities were 0.19, 0.28, and 0.38 g/L/day in control, 4.0 and 8.0 g/L NaHCO3 supplemented groups, respectively. The results indicate that NaHCO3 could be used as a carbon source alternative to CO2 gas for production of Tetraselmis sp. biomass in FC-PBRs. |
