During 1997- 99 one seed samples of each 17 sesame cultivars (totally 17 samples) were collected from 10 localities in Iran. Blotter method and culture media (PDA, PMA, WA, CA, SNA, CLA, CYA, KCLA, WALM, MEA) were used to isolate and identity the mycoflora present on different parts of seeds. Totally, 145 isolates were obtained which included 34 species of 15 genera. The identified fungi were: ...

Secondary metabolites have a great potential as pharmaceuticals, but there are only a few examples where regulation of gene cluster expression has been correlated with ecological and physiological relevance for the producer. Here, signals, mediators, and biological effects of terrein production were studied in the fungus Aspergillus terreus to elucidate the contribution of terrein to ecological...

Phytases catalyse the hydrolysis of phytate (myo-inositol hexakisphosphate) to myo-inositol and inorganic phosphate. In this study genes encoding novel phytases from two different filamentous fungi, Aspergillus terreus strain 9A-1 and Myceliophthora thermophila were isolated. The encoded PhyA phytase proteins show 60% (A. terreus) and 48% (M. thermophila) identity, respectively, to the PhyA of ...

To investigate the structurally novel and bioactive natural compounds from marine-derived microorganisms under high salinity, the fungus Aspergillus terreus PT06-2 was isolated from the sediment of the Putian Sea Saltern, Fujian, China. Three new compounds, terremides A (1) and B (2) and terrelactone A (3), along with twelve known compounds (4-15) were isolated and identified from the fermentat...

The manufacture of enzymes, like L-asparaginase with less adverse effects in the treatment of cancer is an important facet of pharmaceutical industry. Yeast and Filamentous fungi are commonly reported in scientific literature to produce L-asparaginase with less adverse effects than prokaryotic microorganisms. In the present study Latin square design was used to examine the effect of L-proline, ...

background and purpose: otomycosis is an acute, subacute or chronic fungal infection of the pinna, the external auditory meatus and the ear canal caused mainly by several species of saprophytic fungi. lamisil (terbinafine) is an allylamine antifungal agent, that is used both in the topical and oral administration for the treatment of dermatophytosis, cutaneous candidiasis, and the pityriasis ve...

Endoglucanases are important enzymes that are involved in the modification and degradation of cellulose. Filamentous fungi such as Aspergillus terreus are effective biomass degraders in nature owing to their capacity to produce an enzymatic arsenal of glycoside hydrolases, including endoglucanase from glycoside hydrolase family 12 (GH12). The A. terreus GH12 endoglucanase was cloned and overexp...

Optimization of culture conditions for L-asparaginase production by submerged fermentation of Aspergillus terreus MTCC 1782 was studied using a 3-level central composite design of response surface methodology and artificial neural network linked genetic algorithm. The artificial neural network linked genetic algorithm was found to be more efficient than response surface methodology. The experim...

The bioassay-guided isolation and purification of an ethyl acetate extract of Aspergillus terreus MC751 led to the characterization of butyrolactone I as an antidiabetic and antioxidant. The antidiabetic activity of butyrolactone I was evaluated by αglucosidase and α-amylase inhibition assays. Butyrolactone I demonstrated significant concentration-dependent, mixed-type inhibitory activity again...
