초록
미세조류는 이산화탄소를 제거하고 산업적으로 유용한 다양한 이차 대사물질을 생산해 내는 광합성 미생물로 생물산업분야에서 주목 받고 있는 유용한 자원이다. 이러한 미세조류를 실내에서 효과적으로 배양하기 위해서는 무엇보다도 효율적인 광원이 필수적이다. 최근 발달하는 LED광원은 광원의 크기가 작고, 에너지 효율이 우수하며, 특정 파장만 조사할 수 있다는 점 등의 다른 인공광원과 차별되는 많은 장점을 가지고 있다. LED광원을 미세조류의 배양에 적용하는 연구는 최근에 와서야 점차 시도되고 있는 실정이며, 아직까지 실험실 규모의 실험과 대표적인 특정 종 위주의 결과들만 나오고 있어, LED광원을 미세조류의 산업적인 배양에 적용하기 위해서는 더 많은 세부적인 연구 결과가 요구된다. 하지만 LED 조명을 미세조류 배양 분야에 적용하는 것은 효과적인 접근으로 생각되며, BT(Bio Technology) 산업에 새로운 지평을 열 것으로 생각된다. 따라서 본고에서는 최근 연구되고 있는 LED광원을 이용한 미세조류의 배양 현황 및 그 가능성에 대해서 조사하고, 향후 나아갈 방향에 대해서 기술해 보았다.
Microalgae have been considered as a promising microorganism in the field of bio-industry due to their abilities to fix carbon dioxide as well as biosynthesize valuable secondary metabolites. Of many lighting sources for microalgal cultivation, LED (Lighting Emitting Diode) has been emerged as the appropriate choice with multiple advantages over the conventional bulbs. However, it is only in recent years that we have witnessed the possibility of application of LED into microalgae cultivation system. LED will serve as an evolutionary lighting source for microalgae cultivation system and open the frontier for integrative bio-industries. In this paper, we present the comprehensive review on the recent trends of LED applications into microalgal biotechnology.
