Abstract:
Objective: To screen the endophytic fungi with antimicrobial activity from Glehnia littoralis and identify the taxonomy of these fungi. Methods: The endophytic fungi were isolated from G. littoralis by method of tissue isolation. The oxford-cup test was used in screening the endophytic fungi with antimicrobial activity for Escherichia coli, Staphylococcus aureus, and Candida albicans respectively. And the rDNA ITS1-5.8S-ITS2 sequences were applied for the taxonomy of endophytic fungi. Results: Nineteen strains of fungi with antimicrobial activity were attributed to four genera, five families, seven orders, and eight species. In these fungi, there were four strains with antimicrobial activity to E. coli (the max d/D value was 1.07), Fifteen strains with antimicrobial activity to S. aureus (the max d/D value was 0.65), and three strains with antimicrobial activity to C. albicans (the max d/D value was 1.27). Conclusion: Many kinds of fungi with antimicrobial activity inhabit in G. littoralis. This study is helpful to develop the recourses of endophytic fungi and to evaluate the genuineness of G. littoralis.
