Offshore cultivation has various advantages such as mixing from waves and large cultivable area. In this study, serial tubular photobioreactors (ST-PBRs) were used for cultivating a green microalga, Tetraselmis sp. MBEyh01L in the nearshore of Young-Heung Island, Incheon, Korea. The seawater temperature was fairly stable at 13.6±1.1ºC while the atmospheric temperature was 19.5±8.3ºC during the culture period. The maximum biomass concentration and biomass productivity were 6.1 g/L and 11.2 g/m2/d, respectively, for 19 days of cultivation. The results showed that ST-PBRs were able to produce microalgal biomass at quite high productivity without any extra energy input, such as electricity for mixing the culture broth and controlling culture temperature. Various geometries and sizes of marine PBRs will be optimized and operated for large-scale microalgal cultivation in the ocean. |
