Abstract

This study aimed to isolate and characterize fungi from freshwater environments in South Korea and evaluate their extracellular enzyme activities. Fungal strains were collected from various freshwater sources and identified using phylogenetic analysis. The isolated fungi included known aquatic hyphomycetes and previously unreported species. Extracellular enzyme, including those of protease, amylase, lipase, cellulase, laccase, and chitinase, activities were evaluated. Among the isolated strains, several showed high enzyme activity, suggesting their potential role in organic matter decomposition in freshwater ecosystems. This research expands our knowledge of the diversity and enzyme activities of the fungi in freshwater environments, contributing to our understanding of their ecological roles.

본 연구는 담수 환경에서 분리한 곰팡이의 특성을 알아보기 위해 효소 활성을 평가하였다. 40개의 곰팡이들은 다양한 담수 시료로부터 분리되었으며, 계통분석을 통해 동정하였다. 실험에 사용된 균주들은 최근에 국내에 보고되었거나, 아직 보고되지 않은 종으로서 이에 대한 특성 정보가 거의 알려지지 않았다. 본연구에서는 40개 균주를 대상으로 protease, amylase, lipase, cellulase, laccase, chitinase의 효소에 대해서 활성을 검정하였다. 대부분의 균주가 laccase 활성을 보였으며, protease, amylase 순으로 높게 나타났다. 담수 환경에서의 효소 활성 정보는 이들의 생태적 역할을 이해하고 산업적으로 활용하는데 기여할 수 있을 것이다.
