Diversity of Rhizosphere Soil Fungi of Aegiceras corniculatum and their Antibacterial Activities
摘要
Abstract
[Objective]To investigate the diversity of rhizosphere soil fungi of Aegiceras corniculatum and the anti-bacterial activity of their fermentation products.[Methods]The cultivable fungi in the rhizosphere soil of Aegiceras cor-niculatum were isolated by the dilution plating method.The fungi strains were identified based on ITS rDNA sequence alignment.The antibacterial activities of the fermentation products of these fungi strains were evaluated by the filter pa-per agar diffusion method and microplate method.[Results]A total of 40 cultivable fungal strains isolated and identi-fied from the rhizosphere soil of Aegiceras corniculatum belonged to 3 classes,5 orders,7 families,and 11 genera.Spe-cifically,there were 14 strains of Penicillium,13 strains of Talaromyces,5 strains of Aspergillus,1 strain of Fusarium,1 strain of Humicola,1 strain of Trichoderma,1 strain of Scedosporium,1 strain of Westerdykella,1 strain of Neoroussoella,1 strain of Emericellopsis,and 1 strain of Trichosporiella.The fermentation products of 22 strains exhibited inhibitory ef-fects on at least one pathogenic bacterium.[Conclusion]The rhizosphere soil fungal community of Aegiceras cornicula-tum has rich diversity and possesses the potential value for developing antibacterial natural products.关键词
