시안세균 생장 억제 곰팡이의 분리 및 동정 = Isolation and Identification of Fungi that Inhibiting the Growth of Cyanobacteria

다국어 초록 (Multilingual Abstract)

Cyanobacteria (Anabaena cylindrica) lytic fungi were isolated from 4 reservoirs located in Kyonggi-Do, Korea. These isolates from Wangsong reservoir shown in eutrophication, were identified the genera Acremonium sp., and Penicillium sp. by morphological characters. The Penicillium sp. generally showed less algal lytic activity than the Acremonium sp. on the Anabaena cylindrica agar lawn, but the cultured supernatant of Penicillium sp. exhibited greater activity than the Acremonium sp. on Micrococcus luteus. In the mixed culture of Anabaena cylindrica and HCLF-34, the algae was segmented and lysed in 3 days. On the other hand, Anabaena cylindrica was aggregated, segmented, and lysed within 3 hours in the mixture of Anabaena cylindrica and the supernatant of HCLF-34. In addition, Anabaena cylindrica was segmented and the width sheath of Anabaena cylindrica was lysed on Scanning Electron Microscopy, in mixed culture of the algae and the fungi on agar plate.
