Introduction: In our previous study, secondary metabolites of endophytic fungi isolated from gall rust sengon showed their bioactive activity against antibacterial and antioxidant, but only gave little effect to antifungal activity. Endophytic fungal culture extracted from gall rust of sengon (Falcataria moluccana Miq. Barneby and J. W. Grimes) has the ability on inhibiting Bacillus subtilis, Pseudomonas aeruginosa and Escherichia coli. To increase the production of bioactive compounds, this research was focused on isolates which produced the highest activity compounds, and sought the optimal fermentation conditions in the production of bioactive compounds. Methods: The fermentation process was carried out on PDB liquid media for 21 days, under shaker conditions, at room temperature, and sampling measurements were hold every 3 days. Bioassay were carried out against B. subtilis, P. aeruginosa, and E. coli. Results: The early stages fungal growth was adaptation stage, continued by 1-6th days of exponential growth period. Day 6-12th was stationary growth and day 15-21th were cell death periode. The highest secondary metabolite production was achieved at stationary periodes, that was occured at days 9-15th\ and high antibacterial activity was produced on days 9-12th. Conclusion: The best production secondary metabolite that has high activity was at day 9-12th.

Introduction: Endophytic fungi are becoming an important source of new natural bioactive products. Many interesting endophytic fungi have been isolated from traditional medicinal plants. Crocus sativus L. (saffron) is one of the most expensive and rarest spices in the world, used as a dye, aroma and for medicinal purposes. This study reports on the molecular characterization of endophytic fungi isolated from roots of saffron plants growing in Taliouine- Morocco, and the examination of the antibacterial and antioxidant activities of secondary metabolites extracted from these endophytes. Methods and Material: The fungi were isolated from sterilized saffron root fragments and identified using internal transcribed spacer (ITS) rRNA gene sequence analysis. Three endophytes were fermented and extracted with ethyl acetate (EtOAc) and chloroform (CHCl3). The antibacterial activity of fungi extracts was evaluated using the Agar Diffusion Method against six strains, Bacillus sp., Stenotrophomonas sp., Pseudomonas putida, Pantoea sp., Luteibacter sp. and Escherichia coli. The antioxidant activity was tested by using the \α,\α-diphenyl-\β-picrylhydrazyl (DPPH) analysis and \β-Carotene bleaching test (BCBT) methods. Results: Sixty fungal isolates were recovered and purified from saffron roots. ITS rDNA sequences were 99-100\% identical to three different species: Rhizopus oryzae, Aspergillus fumigatiaffinis and Aspergillus niger. Both Rhizopus oryzae extracts had high antibacterial activity against most of the bacteria tested, while Aspergillus niger and Rhizopus oryzae extracts showed an antioxidant capacity using DPPH and BCBT methods, respectively. Conclusion: The fungal endophytes inhabiting saffron roots could be a potential source of natural plant bioactive secondary metabolites especially for antibacterial and antioxidant purposes.

The Mikania laevigata (Asteraceae) is a Brazilian medicinal plant used to treat respiratory tract diseases.It is produced on a large scale for phytotherapic formulation. No studies on the endophytes of Mikania laevigata have been described in the literature. The endophytic fungi isolated from the leaves of M. laevigata cultivated in a floral garden located in the south region of the Bahia state, Brazil, were investigated. After surface disinfection, the performing the isolation procedure, a total of forty endophytic fungi were obtained and grouped into different morphospecies. The fungi were characterized by molecular sequencing the ITS rDNA regions, and they were identified by comparing the results published Gen Bank sequences.The phylogenetic analyses revealed four major clades of fungi from the sequenced ITS-rDNA regions: Nodulisporium sp. (3 isolates), Hypoxylon sp.(3 isolates), Daldinia sp. (1isolate) and Xylaria luteo stromata (aunique isolate).The Xylariaceae Genus was the dominant group of fungi associated with Mikania laevigata.

Key words:Mikania laevigata, Asteraceae, Xylariaceae, Endophytic fungi.
