초록

미세 조류의 항균성 탐색을 위해 베를린 공대 생물공학 연구실에서 좀 균주을 분양받아 독일 현지 연구실에서 연구를 행하였다. 6종의 미세 조류로부터 항균성 시험 시료응 획득하기위해 먼저 배양데 따른 미세 죠류 배양액의 변화를 pH와 균제량으로 관찰하였고, 이를 토대로 시험 시료를 대주중식기와 정기기 두 구간으로 나누어 채취하였다. 얻어진 시료를 균체와 균체 상층액으로 분리하여 각족 용매를 이용하여 분획을 행하여 4-7종의 획분들 얻었거 이들이 가지는 항균 활성을 시험하였다. BGA(blue green algae) 4종류 중에서 Lsp(lyngbya sp.)와 Tsp(Tetraselmis sp.)에서 항균활성이 관측되었는데, 특히 균체외 상층액의 dthyl acetate 추출 획분이 서균과 특히 곰팡이에 대해 강력한 항균 활성이 있는 것으로 확인되었고, 그뢰 2종의 BGA 와 2종의 규조류(diatoms)에서는 항균 활성 획분이 확인되지 않았다.

As a part of the investigation on useful compounds from microalgae, and its recently that marine planktonic algae have been recognized as potial sources of antibacterial and antifungal substances, we searched for antimicrobial active compounds from the extracts of six microalgae-Lyngbya sp., Tetraselmis sp., Microcystis sp., Chlorella sp., Navicula sp. and Rhalassiosira sp.-treated with several solvents. There were two active species-Lyngbya ap., Teraselmis sp.- in the antimicrobial activity test to bacteria, yeast and molds, especially the activity existed in the extracts by ethyl acetate of supernatants to the microalgae incubatio. and there won’t any activity in two diatoms to the test microorganism.
