Endophytic fungi are known to be a rich source of anti-infective drugs. In our study, was investigated for fungal diversity using different media to give 11 isolates which were identified morphologically. Out of the isolated fungal strains, sp. (LCEF10) revealed potential anti-infective activity against the tested microbes ( ATTC 25922, aeruginosa (ATTC 29231), ATTC 27853 ATTC 10231), besides, their MICs were measured by well diffusion method, therefore, it was subjected to molecular identification in addition to phylogenetic analysis. Moreover, the ITS sequence of strain LCEF10 showed a consistent assignment with the highest sequence similarity (99.81%) to NRRL 787. The crude ethyl acetate extract of sp. LCEF10 was investigated for metabolomic analysis using LC-HR-ESI-MS. The metabolic profiling revealed the presence of polyketides, macrolides, phenolics and terpenoids. Furthermore, molecular docking study was carried out to predict which compounds most likely responsible for the anti-infective activity.
内生真菌被认为是抗感染药物的丰富来源。在我们的研究中,使用不同的培养基来研究真菌多样性,共分离出 11 株真菌,通过形态学鉴定进行了鉴定。在所分离的真菌菌株中, sp. (LCEF10) 对测试的微生物(ATTC 25922、 aeruginosa (ATTC 29231)、 ATTC 27853 ATTC 10231)表现出潜在的抗感染活性,此外,还通过微孔扩散法测量了它们的 MIC,因此,除了进行系统发育分析外,还对其进行了分子鉴定。此外,菌株 LCEF10 的 ITS 序列与 NRRL 787 的最高序列相似性(99.81%)一致。对 sp. LCEF10 的粗乙酸乙酯提取物进行代谢组学分析,采用 LC-HR-ESI-MS。代谢分析显示存在聚酮类、大环内酯类、酚类和萜类化合物。此外,还进行了分子对接研究,以预测哪些化合物最有可能具有抗感染活性。
