Endophytes, a potential source of bioactive secondary metabolites, were isolated from the widely used medicinal plant Ait. Approximately 675 segments from 15 plants and 15 latex samples were assessed for the presence of endophytic fungi. Finally, eight fungal species were isolated and identified based on their macro- and micro-morphology. The endophytic fungal filtrates were screened for their antimicrobial activity against 11 important pathogenic micro-organisms. The filtrates of nanoparticles were from three of the eight isolated endophytic fungi, namely, and , and were highly effective against the tested bacteria, while the remaining endophytic fungal filtrates displayed low activity.
内生真菌是生物活性次生代谢产物的潜在来源，从广泛使用的药用植物 Ait 中分离出来。评估了大约 15 株植物和 15 个乳胶样本的 675 个片段中内生真菌的存在情况。最后，根据宏观和微观形态学特征，分离和鉴定了 8 种真菌。对内生真菌滤液进行了抗 11 种重要致病微生物的抗菌活性筛选。从 8 种分离的内生真菌中的 3 种（即 和 ）的纳米颗粒滤液对测试的细菌具有很高的有效性，而其余内生真菌滤液的活性则较低。
