| dc.description.abstract | In the present study, we were interested in studying the amylolytic and antibacterial activity of some filamentous fungi isolated from the rhizosphere of cultivated plants in Tamanghasset region. Consequently, 11 pure strains belonging to the different fungal genera were isolated Alternaria, Aspergillus, Cladosporium, Curvularia, Fusarium, Mucor and Penicillium. Positive result of amylolytic activity was revealed on all the isolated strains, with important hydrolysis zones of 54.33 ± 1.15 mm, 54.00 ± 3.61 mm, 52.00 ± 6.08 mm and 51.33 ± 15.01 mm for Aspergillus sp.1, Curvularia sp., Fusarium sp.2 and Mucor sp. respectively. In addition, analysis of variance (ANOVA) of the means of hydrolysis zones diameters shows that the values linked by the same letter do not show any significant difference at P < 0.05. Antibacterial activity of the isolated fungal was demonstrated by the agar cylinder technique against four pathogenic bacterial strains. The results showed a variability of the inhibition zones, thus the most important results were recorded against S. aureus, E. coli and K. pneumonia for all fungi which produced inhibition zones ranging from 15.33 ± 0.00 to 23.66 ± 1.71 mm. while all isolate had the lowest inhibition zone against P. aeruginosa. In conclusion, the obtained results indicated the isolated filamentous fungi have the potential to inhibit the four pathogenic bacterial strains, S. aureus, E. coli, K. pneumonia and P. aeruginosa, while simultaneously showed significant amylolytic activity. | |
