Contamination Control in the Culture of Marine Microalgae Tetraselmis sp. using Hypersaline Seawater as Culture Medium |
| 초록 |
Microalgae are one of the promising feedstocks for production of biodiesel to replace fossil fuels. Cultivation of marine microalgae using seawater can substantially reduce freshwater consumption in microalgal biofuels production. Seawater can contain various biological contaminants that may decrease algal biomass and fatty acid productions. In this study, use of hypersaline culture medium for preventing contamination in the culture of Tetraselmis sp. MBEyh04Gc (KCTC12432BP) was investigated. Culture media with different salinities were prepared by addition of sodium chloride to natural seawater, and the microalgae were cultivated in 400-mL bubble column photobioreactors. Increased salinity not only prevented contamination, but also increased fatty acid contents and biomass productivity. The highest fatty acid productivity, 22.4 mg/L/d, was obtained with 80 PSU. The results of this study indicate that increasing the salinity could be an effective method to control contamination in microalgal biomass production. |
