从药用植物小桐子的根和茎中分离到内生真菌57株,经鉴定,它们分属于15个不同的分类单元。其中拟盘多毛孢为优势属,其次为拟茎点霉属和茎点霉属。用杨桃炭疽菌,香蕉疫霉和镰刀菌作指示菌对这些内生真菌的抗真菌活性进行检测,结果表明,有2株菌对杨桃炭疽菌具有抑菌活性。 57 endophytic fungi were isolated from the roots and stems of medicinal plants, Jatropha curcas, and they were identified as belonging to 15 different taxa. Among them, Pestalotiopsis sp. Was the dominant genus, followed by Phytophthora and Phytophthora sp. The antifungal activity of these endophytic fungi was detected by using carambola anthrax, Phytophthora capsici and Fusarium as indicator bacteria. The results showed that two strains had antibacterial activity against Carambola anthrax.
