Abstract

Endophytic fungi are ubiquitous in plants and reside their hosts for a part of their life cycle. Their various diversity associated with the potential bioactivity has played an important role in human health, especially that from Chinese traditional medicinal herbs. Here, we isolated endophytic fungi from plant Curcuma wenyujin and evaluated their antimicrobial activity. Sixty-six endophytic fungi were recovered from the fresh and healthy root, leaf and stem tissues of C. wenyujin. Of these isolates, the common species Penicillium, Fusarium and Aspergillus were the dominant species. 65% of endophytic fungi had the potential antibacterial activity against one or more tested microorganism of E. coli, P. vulgaris, B. subtilis, S. aureus, Rhizopus, Microzyme, A. niger and Mucor, and 4.5% strains could inhibit eight tested microbes, exhibiting a broad antimicrobial spectrum. These findings provide a strong platform for the isolation and purification of natural antimicrobial agents from endophytic fungi of C. wenyujin.
