Global temperatures are steadily increasing, leading to significant changes in microbial diversity and ecology. In the present study, we isolated high-temperature-growing fungi and fungi-like group (Oomycota) strains from freshwater environments of Korea and identified them based on cultural, morphological, and multilocus phylogenetic analyses. As a result, we introduce (Fungi) isolates as a new species, sp. nov. and record and (Oomycota) new to Korea. In the growth experiments, they exhibited high-temperature tolerance, which can grow at 35-40 °C but become inactive at 4 °C and below. This study confirms the presence of high-temperature-tolerant fungi and oomycetes in Korea and suggests that the Korean climate conditions are changing in favor of these species. This indicates that climate warming is altering microbial distributions in freshwater environments.
全球气温正在稳步上升，导致微生物多样性和生态发生重大变化。在本研究中，我们从韩国的淡水环境中分离出高温生长真菌和类真菌群（卵菌纲）菌株，并通过培养、形态学和多位点系统发育分析对它们进行了鉴定。结果，我们将（真菌）分离物作为一个新物种引入，即新种。并记录了在韩国首次发现的和（卵菌纲）。在生长实验中，它们表现出高温耐受性，能在35-40°C下生长，但在4°C及以下则失去活性。本研究证实了韩国存在耐高温真菌和卵菌，并表明韩国的气候条件正在朝着有利于这些物种的方向变化。这表明气候变暖正在改变淡水环境中的微生物分布。
