Screening of Antibacterial Activities of Endophytic Fungi Isolated from Ficus carica

With Staphylococcus aureus,Bacillus subtilis,Escherichia coli as the test species,the Ficus carica roots,stems and leaves of 87 isolated strains of endophytic viable fungi were screened. The results showed that:87 endophytic fungi have 36 pairs of one or more indicator bacteria have antagonistic effects;one of the Staphylococcus aureus inhibition of 18 strains of Bacillus subtilis have antimicrobial effect 11 strains of Escherichia coli have inhibitory effects on the 7 strains isolated strains to moderate antibacterial activity and more activity-based,high activity and low activity strains less. There is activity from the 36 selected representative strains of 20 strains of endophytic fungi metabolites of antimicrobial activity screening. The results showed that:20 strains of metabolites at least one kind of test bacteria with antibacterial activity.
