초록

봄철 cyanobarteria가 우점하는 천호지에서 fluorescent in situ hybridization (FISH) 방법을 이용하여 세균군집구조를 조사하였다. 조사기간동안 총세균수는 0.6~$1.3{\times}10^7 \cells{\cdot}ml^-1$ 의 범위로 매우 높게 나타났다. 또, 총세균수에 대한 eubacterial group이 차지하는 비율의 경우 29.8~45.8%로 작은 분포를 차지하였다. 세균군집구조를 분석한 결과, $\alpha$-group은 1.4~l2.5%, $\beta$-group은 0.9~4.9%, $\gamma$-group은 0.6~8.3%, $\circledcirc$Cytophaga-Flavobacteruim group은 1.0~8.3%를 나타내어 본 연구에서 조사된 각 group이 차지하는 비율은 낮고 상대적으로 unknown eubacteria의 비율이 높았다. 이러한 군집구조는 일반적으로 다른 담수호에서 나타나는 세균의 군집구조와는 다른 군집구조 이며 특히, aggregates에 부착한 세균 군집구조와 비슷한 양상이었다. 또, cyanobacteria의 조성 이 Anabaena속에서 Microcystis속으로 천이가 일어난 시기에 Cytophaga-Flavobacteruim group이 크게 증가하는 것으로 나타나 세균군집의 크기는 식물플랑크톤의 영향을 받는 것으로 확인되었다.

The composition of bacterial communities was detected in surface water of Cheonho Reservoir dominated by cyanobacteria, using fluorescent in situ hybridization (FISH) method. Total bacterial numbers were very high ranging from 0.6~$1.3{\times}10^7 \cells{\cdot}ml^-1$, whereas the ratio of Eubacteria to total bacteria was 29.8~45.8%, which was lower than that in other freshwater ecosystems. On average only 2.1% of DAPI-stained bacteria were detected by FISH with probes for $\alpha$, $\beta$, and $\gamma$-groups, respectively. Unknown eubacteria which was not bound to any probes except EUB 338, was relatively high. On the other hand, the Cytophaga-Flavobacterium group increased following the change of dominant species from Anabaena sp. to Microcystis sp. This result showed that bacterial communities could be affected by phytoplanktons, especially cyanobacteria.
