The two-stage light cultivation process for the production of astaxanthin under autotrophic conditions using the sun during outdoor cultivation comprising inoculating mature spore (cyst) cells and adding iron ions, according to the present invention, can solve the problem that synthesis of astaxanthin is inhibited by excess generation of LROS(O2-, H2O2) by effectively converting LROS(O2-, H2O2) that is generated in a large amount under high-temperature conditions to MROS(O2, OH·) and amplifying an intracellular lipid oxidation signal, thereby more economically increasing the production of astaxanthin.

Le processus de mise en culture sous lumière à deux phases pour la production d'astaxanthine dans des conditions autotrophes à l'aide de la lumière du soleil lors de la mise en culture en extérieur consistant à inoculer des cellules sporales (sporocyste) mûres et à ajouter des ions de fer, selon la présente invention, permet de résoudre le problème selon lequel la synthèse de l'astaxanthine est inhibée par génération excessive de LROS(O2 -, H2O2), en convertissant efficacement les LROS(O2 -, H2O2) qui sont générées en grande quantité dans des conditions de haute température en MROS(O2, OH·) et en amplifiant un signal d'oxydation de lipides intracellulaires, ce qui permet d'augmenter de manière plus économique la production d'astaxanthine.

본 발명에 따르면, 옥외배양 시 자가영양조건으로 태양을 이용한 아스타잔틴 생산에서 성숙 포자(cyst) 세포를 접종한 후 철이온을 첨가하는 이단(two-stage) 광배양 공정은 고온의 조건에서 다량 발생되는 LROS(O2-, H2O2)를 효과적으로 MROS(O2, OH·)로 전환하여 세포 내 지질 산화 신호를 증폭하여 LROS(O2-, H2O2)의 과량 발생에 의한 아스타잔틴 합성을 저해하는 문제점을 해결할 수 있으므로, 보다 경제적으로 아스타잔틴 생산을 증진시킬 수 있고 이러한 아스타잔틴은 강력한 항산화물질로서 다양한 산업분야에서 유용하다.
