The carotenoid profile of SH104 and SHG104 was ОІ-carotene, astaxanthin, canthaxanthin, pheonicoxanthin and echinenone, which analyzed by HPLC and LC/APCIвЂ“MS. SHG104 were palmitic acid and a trace of other long-chain fatty acids. In addition to DHA, the main fatty acids produced by Schizochytrium sp. SHG104 yielded 10.8В g L в€’1 of biomass comprising 45.8% total lipids (32.1% DHA) and 4.6В mg L в€’1 of astaxanthin. Under combined temperature-shift cultivation conditions employing white-light LEDs (light-emitting diodes), Schizochytrium sp. An improved Schizochytrium mutant, named SHG104, was obtained from the original host strain by Оі-irradiation-induced mutagenesis. through 18S rRNA analysis and named SH104, simultaneously produces high levels of DHA and carotenoid-based antioxidant pigments. This newly isolated Thraustochytrid, identified as Schizochytrium sp. In the present study, we describe the isolation and characterization of a new Thraustochytrid Schizochytrium sp. Results to date suggest that microalgal Thraustochytrids family strains can be used to produce high-functional omega-3 rich oil (~вЂ‰30вЂ“70% of dry cell weight) and carotenoid-based antioxidant pigments simultaneously with value-added bioactive potential.
