In this study, Schizochytrium sp. SH104 isolated from the west coastal area of Korea was used to establish the culture conditions to increase the carotenoids production without decreasing docosahexaenoic acid (DHA) production. SH104 was cultured at 28℃ for 2 day and then cultured at 20℃ for 2 day under light emitting diode (LED). Lowering the temperature during incubation time, affects the increase of carotenoids production. In addition, SHG104 was created by gamma-ray mutagenesis of SH104, and carotenoid production of SHG104 was confirmed under the same culture conditions. The production of astaxanthin and beta-carotene using SHG104 strain was 6 fold and 7 fold higher, when compared to SH104. These results suggest that carotenoid productivity would be increased by optimized culture condition and gamma-ray mutagenesis of Schizochytrium.
