Photobioreactors (PBRs) might be designed for successful offshore cultivation of microalgae. In this study, Serial Tubular photobioreactors (ST-PBRs) were used for cultivating a green microalga, Tetraselmis sp. MBEyh01L, in the coastal water of Young-Heung Island, Incheon, Korea. The seawater temperature was relatively stable at 13.6±1.1ºC while atmospheric temperature was 19.5±8.3ºC during culture periods. The maximum biomass concentration and productivity were 6.1 g/L and 11.2 g/m2/day for 19 days, respectively. This results indicate that ST-PBRs are suitable for producing microalgal biomass at high productivity without any extra input energy such as electricity for mixing the culture broth and controlling culture temperature. In addition, development of marine PBRs with efficient conversion of wave energy into culture mixing will be contribute to improve biomass productivity in ocean-based microalgal cultivation. |
