Antimicrobial activity of filamentous fungi isolated from soil at parks in Ho Chi Minh City, Vietnam

Abstract

This study has isolated 103 species of fungi from soil at parks in Ho Chi Minh city, including 69 species of Penicillium sp., Aspergillus sp., Trichoderma sp., Mucor sp., Fusarium sp., Phoma sp., Curvularia sp ., Paecilomyces sp., and Cladosporium sp., and other 34 unknown species. Antimicrobial activities of these fungi were investigated on Staphylococcus aureus, MRSA, Streptococcus feacalis, Escherichia coli, and Pseudomonas aeruginosa, Candida albicans, C.glabrata and C.tropicalis. Among them, 27 species possess antibacteria, including 10 Penicillium sp., 11 Aspergillus sp., 3 Trichoderma sp. and 3 unidentified species and other 12 species showed anti-fungi effects, including 2 Penicillium sp., 1 Aspergillus sp., 1 Trichoderma sp. and 8 unidentified species. Especially, 3 species belonging to Penicillium sp. T33, Aspergillus sp. G51 and  H34 exhibited both antibacterial and anti-fungi abilities. In addition, culture medium containing yeast and corn extracts is appropriate for the growth of fungi. These results indicated that fungi from soil are  a potential source of novel antimicrobial agents
