Abstract：
145 fungal isolates were obtained from three sampling sites situated within the Nam River basin, located in the southern region of South Korea. Through ITS sequence analysis, the fungal isolates were identified to comprise 55 species of ascomycetes and 11 species of basidiomycetes. The 55 species of ascomycetes exclusively belong to the phylum Pezizomycotina, comprising 33 species of Dothideomycetes, 6 species of Eurotiomycetes, and 16 species of Sordariomycetes. Regarding their plant pathogenicity, an investigation into the fungi\'s ability to penetrate solid media revealed Nigrospora chinensis as displaying the highest growth, followed by Pseudopestalotiopsis theae, various Curvularia species, Diaporthe species, and Alternaria alternata. Further research associating this penetration ability with fungal pathogenicity is deemed necessary. Among the 10 fungal species exhibiting penetration abilities, an examination of their capability to degrade biological polymers revealed that two strains of D. phaseolorum displayed exceptional polymer degradation. These strains exhibited remarkable abilities in decomposing malachite green and crystal violet, both recalcitrant dyes. This study underscores the potential utilization of fungal diversity in freshwater environments as a foundational approach to address freshwater pollution issues.
摘要：
从位于Nam河流域内的三个采样点获得145种真菌分离物，位于韩国南部地区。通过ITS序列分析,真菌分离株包括55种子囊菌和11种担子菌。子囊菌的55种完全属于Pezizomcotina门，包括33种杆菌属，欧洲真菌6种，和16种梭菌。关于它们的植物致病性，对真菌穿透固体培养基的能力的调查显示，黑孢菌表现出最高的生长，其次是假雌蕊，各种弯孢菌，Diaporthe物种，和链格孢菌.将这种渗透能力与真菌致病性相关联的进一步研究被认为是必要的。在10种具有穿透能力的真菌中，对它们降解生物聚合物的能力的检查表明，两株D.phaseolorum表现出异常的聚合物降解。这些菌株在分解孔雀石绿和结晶紫方面表现出显著的能力，两种顽固的染料。这项研究强调了在淡水环境中真菌多样性的潜在利用，作为解决淡水污染问题的基础方法。
