| Abstract: | Objective The biotransformation of vancomycin by endophytic fungi isolated from Paris polyphylla var. yuunanensis （Franch.） Hand.-Mazz was studied. Methods Endophytes were isolated and screened for their biotransformational abilities. Afterwards, these endophytic fungi having transformation abilities were identified. Results Two strains of the endophytic fungi were able to transform vancomycin. Based on their 26S rDNA or ITS sequences, they were identified as Penieillium ehrysogenum and Fusarium nematophilum. After strains G01 and G03 cultivated for 6 days in liquid media containing vancomycin, the peak area of vancomycin decreased and new absorption peaks appeared according to the high performance liquid chromatography （HPLC）. Conclusion Some new components were produced by fermentation of the two stains of endophytic fungi. |
