| clavatol and patulin formation as the antagonistic principle of aspergillus clavatonanicus, an endophytic fungus of taxus mairei. | many endophytic fungi are known to protect plants from plant pathogens, but the antagonistic mechanism has rarely been revealed. in this study, we wished to learn whether an endophytic aspergillus sp., isolated from taxus mairei, would indeed produce bioactive components, and if so whether (a) they would antagonize plant pathogenic fungi; and (b) whether this aspergillus sp. would produce the compound also under conditions of confrontation with these fungi. the endophytic fungal strain from t. m ... | 2008 | 18317751 |
| determination and production of antimicrobial compounds by aspergillus clavatonanicus strain mj31, an endophytic fungus from mirabilis jalapa l. using uplc-esi-ms/ms and td-gc-ms analysis. | endophytic fungi associated with medicinal plants are reported as potent producers of diverse classes of secondary metabolites. in the present study, an endophytic fungi, aspergillus clavatonanicus strain mj31, exhibiting significant antimicrobial activity was isolated from roots of mirabilis jalapa l., was identified by sequencing three nuclear genes i.e. internal transcribed spacers ribosomal rna (its rrna), 28s ribosomal rna (28s rrna) and translation elongation factor 1- alpha (ef 1α). ethyl ... | 2017 | 29049321 |
| alpha-l-rhamnosidase from aspergillus clavato-nanicus mtcc-9611 active at alkaline ph. | an alpha-l-rhamnosidase secreting fungal strain has been isolated and identified as aspergillus clavato-nanicus mtcc-9611. the enzyme was purified to homogeneity from the culture filtrate of the fungus using concentration by ultrafiltration membrane and ion-exchange chromatography on cm-cellulose. the native page analysis confirmed the homogeneity of the purified enzyme. the sds-page analysis of the purified enzyme revealed a single protein band corresponding to the molecular weight 82 kda. the ... | 2012 | 22834305 |
