L-asparaginase production was investigated in the filamentous fungi Aspergillus tamarii and Aspergillus terreus. The fungi were cultivated in medium containing different nitrogen sources. A. terreus showed the highest L-asparaginase (activity) production level (58 U/L) when cultivated in a 2% proline medium. Both fungi presented the lowest level of L-asparaginase production in the presence of g...

The antioxidant, antifungal and antibacterial potentials of volatile oils and oleoresin of Cinnamomum zeylanicum Blume (leaf and bark) were investigated in the present study. The oleoresins have shown excellent activity for the inhibition of primary and secondary oxidation products in mustard oil added at the concentration of 0.02% which were evaluated using peroxide, thiobarbituric acid, p-ani...

Amphotericin B therapy continues to be the "gold standard" in the treatment of invasive aspergillosis in the immunocompromised host. Although Aspergillus fumigatus and Aspergillus flavus constitute the major species, several reports have described invasive pulmonary or disseminated disease due to the less common Aspergillus terreus and dismal clinical outcomes with high-dose amphotericin B. We ...

Social concern and awareness of the potential risk posed by environmental residues of antibiotics such as gentamicin in the development of antibiotic resistance genes have increased. The present study used laboratory-scale experiments to develop methods for gentamicin removal from the environment. A fungus, strain FZC3, which could remove gentamicin in submerged fermentation, was isolated from ...

Investigation of EtOAc extract from the fermentation broth of the fungus Penicillium oxalicum led to the isolation of a xanthone, secalonic acid D, which showed good antitumor activity both in vivo and in vitro. The docking study revealed that secalonic acid D could block the active pocket of topoisomerase І with seven hydrogen bonds between secalonic acid D and ARG488, LYS532, ASP533.

Rice is a staple food for over half of the world’s population, and fungal spoilage in stored rice may occur when moisture content temperature are conducive. Aspergillus sp. Penicillium most harmful toxigenic species that produce mycotoxins. Molds pose potential threat to public health cause huge economic loss. Therefore, it great importance find out how molds multiply rice. This study focused o...

Two expression plasmids designed to produce the rotaviral VP6 protein in Aspergillus nidulans and Aspergillus terreus have been constructed. In one of these plasmids the inducible A. terreus Gla1 glucoamylase gene promoter and Gla1 signal sequence are fused to the VP6 cDNA to enable induction and extracellular secretion of the final protein product; in the other, the strong, constitutive A. nid...

To evaluate the effect of fungal inoculants, a pot experiment was carried out on 30 days old transplanted seedlings of Gmelina arborea under nursery condition. Transplants were inoculated with seven day old liquid culture of Aspergillus ellipticus, Fusarium incarnatum, Aspergillus aculeatus, Aspergillus candidus, Penicillium species, Alternaria alternata, Penicillium species, Fusarium javanicum...

The MICs of amphotericin B and itraconazole for 230 isolates of Aspergillus spp., comprising 156 Aspergillus fumigatus, 20 Aspergillus terreus, 22 Aspergillus flavus, 17 Aspergillus nidulans and 15 Aspergillus niger, were determined by a broth microdilution method with RPMI 1640 medium. No isolate was detected with an MIC of amphotericin B >2 mg/L. Itraconazole MICs >16 mg/L were detected for f...
