Antimicrobial and L-asparaginase activities of endophytic fungi isolated from Datura innoxia and Hyoscyamus muticus medicinal plants
Journal Title: European Journal of Biological Research - Year 2016, Vol 6, Issue 3
Abstract
Thirty-six species and two varieties belonging to 16 genera of fungal endophytes were isolated from the leaves of Datura innoxia and Hyoscyamus muticus plants. The most prevailing fungi were: Aspergillus fumigatus, A. niger, A. terreus var. africanus, Cladosporium cucumerinum, C. oxysporum, Penicillium aurantiogriseum and P. chrysogenum. Endophytic fungi from D. innoxia and H. muticus plants were tested for antibacterial and antifungal activities from which 68.98 and 78.26% respectively showed antibacterial against at least one of the tested microbe, but didn’t had effect on tested fungal isolates. Aspergillus niger SVUAn1 was in the top in producing L-asparaginase among tested isolates obtained from two plants. Maximum production of this enzyme obtained after 4 days of incubation with culture medium containing glucose as a carbon source. This study indicated that the endophytic fungi from D. innoxia and H. muticus plant another potential source of bioactive antimicrobial and anticancer agents.
