Omega-3 fatty acids and carotenoids, which are known as representative high-value substances derived from microalgae, are being studied from various diatoms. Most of the diatoms contain fucoxanthin and omega-3 fatty acid. Fucoxanthin produced by diatom has been reported as bioactive compounds exhibiting strong antioxidant, anticancer and anti-inflammatory activities. However, the low growth rate and fucoxanthin content of diatoms are one of the big obstacles to the industrial application. In this study, indigenous marine diatom Achnanthidium sp. BS-001 was isolated for a candidate of fucoxanthin producer. Light intensity and temperature for the culture of Achnanthidium sp. BS-001 were optimized on PhotoBiobox. Optimization of silicate concentration for increasing BS-001 biomass productivity was confirmed in F/2 medium with various concentration of sodium silicate. As a result, condition of light intensity, temperature, and silicate concentration for optimal cultivation were 150 μmol·m<SUP>-2</SUP>·s<SUP>-1</SUP>, 18℃ and 0.106 mM, respectively. Maximum biomass productivity reaches to 154.3 mg·L<SUP>-1</SUP>·day<SUP>-1</SUP>, and then the content of omega-3 fatty acids and fucoxanthin were 19.4 mg·g<SUP>-1</SUP>, 9.05 mg·g<SUP>-1</SUP>, respectively. These results indicate that Achnanthidium sp. BS-001 has the potential to be used as a source of omega-3 fatty acids and fucoxanthin.
