초록

미세조류의 세포벽을 파쇄하여 지질을 추출하는 과정은 에너지를 많이 소비하는 과정으로 알려져 있다. 본 연구에서는 바이러스 감염을 통한 미세조류의 세포벽 파쇄 및 지질 추출법의 효율을 현재 사용되고 있는 마이크로파와 초음파를 이용한 추출법의 효율과 비교하였다. 바이러스 감염을 이용한 지질 생산율은 초음파 및 마이크로파의 생산율과 유의미한 차이를 보이지 않았다. 이는 같은 양의 지질을 낮은 에너지와 비용으로 얻을 수 있을 뿐만 아니라, 클로렐라 바이러스 감염에 의한 미세조류 지질 추출법을 대량 생산 시설에 적용 시 바이오 디젤 생산 비용을 절감할 수 있음을 시사한다.

The most energy-intensive processes in lipids extraction were the disruption of the cell wall of microalgae. Here, we tried to extract lipids through lysis using virus-infecting microalgae, to compare with those by the other two methods using microwave or ultrasonication. The lipids yield using viral infection was not significantly different from those using ultrasonication and microwave oven. This suggests that the same amount of lipids can be obtained with low energy and costs, as well as that microalgal lipids extraction by chlorella virus infection might provide the price competitiveness in biodiesel production even if it will be applied to mass production facilities.
