First, the percentage of cell survival champigjons determined and results were compared to those of untreated controls. Via what appears to be their contribution to the host plant, the endophytes may produce a plethora of substances of potential use to modern medicine, agriculture, and pharmaceutical industry. Artificial inoculation of young switchgrass seedlings with selected bacterial endophytes hold promise as a method of reinfection switchgrass seedlings.

Topical anti-inflammatory activity of Salvia officinalis L. Bioprospecting for microbial endophytes and their natural products.

It has been established that perennial grasses harbour different types of endophytic bacteria and fungi. Mycotoxin production by Chaetomium spp. The compound was previously obtained from several Chaetomium sp.

Based on these observations, compound 2 was identified as the known isocochliodinol which was confirmed by comparison of its UV, 1 H NMR and mass spectral data with published data Sekita, Accordingly, because of their role in conferring plants the ability to adapt to stress conditions, and because they are proven or perceived sources of secondary metabolites with pharmaceutical importance, the study of fungal endophytes is expected to become an important component of endophytea biology Maheshwari, Stems were rinsed in sterilized distilled water twice.

The crude organic extract of the fungal strain was proven to be active when tested for cytotoxicity against LY mouse lymphoma cells. Five and nine different taxa of bacteria and fungi were identified, respectively. Plant material and fungal cnampignons 4 Fresh healthy stems of S.

As controls, media with 0. Material and methods 2. Furthermore, aromatic proton and carbon resonances had ednophytes shifts and multiplicities consistent with the presence of a disubstituted indole residue. As in the case of cochliodinol, the COSY spectrum confirmed that endopbytes isoprenyl group was attached to the aromatic side of the indole substructure since CH 2 -8 exhibited long range correlations of to both H-7 and H Taxonomic identification of the fungus 6 A section 0.

Switchgrass Panicum vergatum L. Plant material and fungal isolation. The yellow MTT penetrates into the living cells and in the presence of mitochondrial dehydrogenases, MTT is transformed to a blue formazan complex. A total of endophytes isolates were recovered 52 bacteria and 93 fungi from whole plant samples ejdophytes at early vegetative, and full reproductive stages. Rice culture of isolated fungus.

The material was placed on a Petri dish malt agar medium containing an antibiotic to suppress bacterial growth medium composition: Results and discussion 18 The crude ethyl acetate extract of rice cultures of Chaetomium sp. The cjampignons intensity is correlated with the number of healthy living cells.

We demonstrate the vertical transmission ability of some endophyte from one switchgrass generation to the next using species-specific primers.

Most diagnostic for unambiguously deducing the position of the isoprenyl side chain proved a correlation of H-4 to C-3 in the HMBC spectrum, the corresponding proton signal was the one exhibiting the meta-coupling, thus representing the proton immediately adjacent to the substituent. Received on February 4,accepted on July 2, Accordingly, correlations of H-2 to both C-3a and C-7a indicated that a further substituent had to reside at C-3 in the heteroaromatic ring of the indole moiety.

Taxonomic identification of the fungus. Evaluation of a tetrazolium-based semiautomated colorimetric assay: Secondary metabolites from endophytic Streptomyces aureofaciens CMUAc and their antifungal activity. Microbial gifts from rain forests. The small amount of ethanol present in the wells did not affect the experiments. Isocochliodinol and neocochliodinol, bis 3-indolyl – benzoquinones from Chaetomium spp.
