Fungal endophytes associated with medicinal plants have potential role to promote plant growth through different mechanisms. However, the biological and ecological roles of fungal endophytes still totally unexplored. In this study, three different fungal endophytes were isolated from the medicinal plant of Asclepias sinaica and identified as Penicillium chrysogenum Pc_25, Alternaria alternata Aa_27 and the third fungal strain was described as sterile hyphae Sh_26. It was recorded that, these endophytes had various ability to produce several extracellular enzymes including amylase, pectinase, cellulase, gelatinase, xylanase and tyrosinase. Their antimicrobial activities against different specific test organisms were investigated as well. In addition, both endophyte isolates i.e. Sh_26 and Aa_27 were found to promote root growth higher than Pc_25 and control treatments. These fungal isolates had a considerable impact on plant growth parameters including root elongation as a result of ammonia and IAA production. ª 2015 Production and hosting by Elsevier B.V. on behalf of Faculty of Agriculture, Ain Shams University.

“…Compounds found in the uninoculated PDA medium (control) are not included in this table and were used to subtract any possible compounds from the medium. Different superscript lower case letters denote statistically significant differences (p < 0.05) between fungal species 2013) and P. canescens (Bertinetti et al 2009;Nicoletti et al 2014) was only explored against phytopathogenic fungi. Studies focusing antimicrobial activity of P. commune against human pathogens are mainly performed with marine sediment-derived strains (Gao et al 2011).…”

species. In the next step, various organic extracts from both A. alternata mycelium and cultured broth were prepared; being ethyl acetate extracts displayed the widest spectrum of anti-microorganisms at a minimum inhibitory concentration ≤0.095 mg/mL. The volatile composition of the fungi that displayed the highest (A. alternata) and the lowest (P. canescens) antimicrobial activity against yeasts revealed the presence of six volatiles, being the most abundant components (3-methyl-1-butanol and phenylethyl alcohol) ascribed with antimicrobial potentialities. Overall the results highlighted for the first time the antimicrobial potential of endophytic fungi from O. europaea and the possibility to be exploited for their antimicrobial agents.Abstract In this study, the antimicrobial potential of three fungal endophytes from leaves of Olea europaea L. was evaluated and the host plant extract effect in the antimicrobial activity was examined. The volatile compounds produced by endophytes were identified by GC/MS and further correlated with the antimicrobial activity. In potato dextrose agar, both Penicillium commune and Penicillium canescens were the most effective inhibiting Gram-positive and -negative bacteria (up to 2.7-fold compared to 30 µg/ mL chloramphenicol), whereas Alternaria alternata was most effective inhibiting yeasts (up to 8.0-fold compared to 25 μg/mL fluconazole). The presence of aqueous leaf extract in culture medium showed to induce or repress the antimicrobial activity, depending on the endophytic Electronic supplementary material The online version of this article

“…All identified taxon in this study, Alternaria (Kjer et al, 2009), Phomopsis (Du et al, 2008, Penicillium (Bertinetti et al, 2009), Pestalotiopsis (Liu, 2011, basidiomycete (Suay et al, 2000) and Streptomyces (Maruna et al, 2010) had already been described as producers of metabolite with antimicrobial activity. Although the TLC method is only qualitative, it is a simple and relatively cheap technique to recognize the inhibitory activity of a large quantity of organic extracts.…”
