13. Endophytic fungus Purpureocillium sp. A5 protect mangrove plant Kandelia candel under copper stress
Abstract Mangrove is an important ecosystem in the world. Mangrove ecosystems have a large capacity in retaining heavy metals, and now they are usually considered as sinks for heavy metals. However, the mechanism of why the soil of mangrove ecosystems can retain heavy metal is not certain. In this research, endophytic fungus Purpureocillium sp. A5 was isolat

14. Cytotoxicity, antioxidant and antibacterial activity of four compounds produced by an endophytic fungus Epicoccum nigrum associated with Entada abyssinica
ABSTRACT Four compounds including beauvericin, parahydroxybenzaldehyde, indole-3-carboxylic acid and quinizarin were isolated from endophytic fungus Epicoccum nigrum and their cytotoxicity, antibacterial and antioxidant activity were evaluated. Beauvericin had remarkable activity against two Gram-negative strains (Bacillus cereus and Salmonella typhimurium)

16. ONE STRAIN-MANY COMPOUNDS (OSMAC) METHOD FOR PRODUCTION OF PHENOLIC COMPOUNDS USING Camarops sp., AN ENDOPHYTIC FUNGUS FROM Alibertia macrophylla (Rubiaceae)
Seven phenolic derivatives including p-hydroxyphenyllactic acid (1), p-hydroxybenzoic acid (2), p-hydroxybenzaldehyde (3), phenyllactic acid (4), n-butyl-3,4-dihydroxybenzoate (5), n-hexyl-3,4-dihydroxybenzoate (6) and n-octyl-3,4-dihydroxybenzoate (7) were produced using Camarops sp. via the one strain-many compounds (OSMAC) approach. Their structures were

17. Annularins I and J: New Metabolites Isolated from Endophytic Fungus Exserohilum rostratum
The paper describes the isolation of ergosterol peroxide, monocerin, annularin I and annularin J compounds of Exserohilum rostratum biomass extracts. Compounds were isolated by silica gel column chromatography in polarity gradient and the structures were determined by nuclear magnetic resonance (NMR) and mass spectrometry (MS) methods. Monocerin, annularin I

18. Compounds of Anthostomella brabeji, an Endophytic Fungus Isolated from Paepalanthus planifolius (Eriocaulaceae)
In this study, fifteen endophytic fungi were isolated from Paepalanthus planifolius (Eriocaulaceae). From the capitula, seven endophytes were screened and evaluated for their metabolomic profile and radical scavenging activity (2,2-diphenyl-1-picrylhydrazyl (DPPH) assay). Chemical investigation of ethyl acetate extract of the endophytic fungus Anthostomella

19. Endophytic fungus strain 28 isolated from Houttuynia cordata possesses wide-spectrum antifungal activity
Abstract The aim of this paper is to identify and investigate an endophytic fungus (strain 28) that was isolated from Houttuynia cordata Thunb, a famous and widely-used Traditional Chinese Medicine. Based on morphological methods and a phylogenetic analysis of ITS sequences, this strain was identified as Chaetomium globosum. An antifungal activity bioassay d

20. Biological properties of Endophytic Fungi
The endophytic fungus is have rich source of secondary metabolites which act as biological active agent in the higher plants. The fungal derivatives play vital part in human life and their compounds are the source of drug for cancer, microbial and viral diseases. The natural compounds from the endophytes acts as growth inhibitor of plant pathogenic organism.

21. Alternariol 9-methyl ether from the endophytic fungus Alternaria sp. Samif01 and its bioactivities
Abstract One bioactive compound, identified as alternariol 9-methyl ether, was isolated from the crude extract of the endophytic fungus Alternaria sp. Samif01 residing in the roots of Salvia miltiorrhiza Bunge. Alternariol 9-methyl ether was active against bacteria with minimum inhibitory concentration values ranging from 25 to 75 µg/mL and median inhibitor

22. Butyrolactones from the Endophytic Fungus Aspergillus versicolor and their Anti-Tobacco Mosaic Virus Activity
New butyrolactones aspernolides C and D, along with two known butyrolactones (A and B) were isolated from the culture of the endophytic fungus Aspergillus versicolor. Their structures were elucidated on the basis of extensive spectroscopic analysis, including 1D and 2D nuclear magnetic ressonance techniques, and electronic circular dichroism. The butyrolacto

23. Characterization and spray drying of lipase produced by the endophytic fungus Cercospora kikuchii
A lipase from the endophytic fungus Cercospora kikuchii was purified, biochemically characterized and the effects of spray drying on stabilization of the purified enzyme were studied. The lipase was purified 9.31-fold with recovery of 26.6% and specific activity of 223.6 U/mg. The optimum pH and temperature were 4.6 and 35 ºC, respectively, while the Vmax w

24. Direct MALDI-TOF/TOF analyses of unnatural beauvericins produced by the endophytic fungus Fusarium oxysporum SS46
The best time of production of the cyclohexadepsipeptide beauvericin by the endophytic fungus Fusarium oxysporum SS46 in Czapek medium was evaluated. The highest level of beauvericin production was found on day 21 of fermentative culture, as assessed by quantitative analysis by high performance liquid chromatography coupled with a photodiode array detector.
