Abstract: 미생물을 건조하지 않고 수분이 있는 상태에서 용매추출법을 이용하여 미생물로부터 오일을 추출하는 경우, 미생물을 건조하여 수분이 거의 없는 상태에서 용매추출법을 시행하는 경우보다 오일 추출 효율이 현저히 떨어진다. 그러나 미생물로부터 수분을 제거하기 위해서는 추가적인 공정비용으로 인하여 바이오디젤 생산비용을 증가시킨다. 따라서 수분이 있는 상태의 미생물로부터 용매추출법을 이용하여 효율적으로 오일을 추출하기 위하여, 미생물-유기용매 혼합용액에 점토를 첨가하여 오일 추출을 진행한다. 일정시간 교반 후 정치시키면 미생물 잔해가 포함된 층과 오일이 포함된 용매층으로 나뉘며, 오일이 포함된 층을 회수하여 유기용매를 제거하고 오일을 얻을 수 있다. 점토를 함유한 유기용매를 이용하여 미생물로부터 추출된 오일은 트리글리세리드 (triglyceride), 디글리세리드 (diglyceride), 모노글리세리드 (monoglyceride), 유리지방산 (free fatty acid)의 형태를 하고 있다. 이러한 오일 성분은 통상적인 바이오디젤 전환 방법인 산촉매 하에서 알콜 (일반적으로 메탄올)을 사용하여 에스테르화/전이에스테르화 반응을 통하여 바이오디젤로 전환이 가능하다.
