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...

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...

OBJECTIVE The evaluation of the Sensititre YeastOne and Etest methods for determining susceptibility to amphotericin B and itraconazole by comparing the MICs obtained by these methods at different times of reading with those of the M38-A broth microdilution method. METHODS Sixty-three clinical isolates of Aspergillus spp. (23 Aspergillus flavus, 24 Aspergillus fumigatus, nine Aspergillus nige...

BACKGROUND Aspergillus terreus is an evolving opportunistic pathogen, and patients with A. terreus often have poor outcomes due to its intrinsic resistance to several systemic antifungal agents. Here we present a unique case of intracranial abscesses of A. terreus in a patient with recurrent angiosarcoma, complicated by development of tension pneumocephalus. CASE REPORT A 67-year old gentleman ...

Fungal xylanases has important applications in food, baking, pulp and paper industries in addition to various other industries. Xylanases are produced extensively by both bacterial and fungal sources and has tremendous potential of being active at extremes of temperature and pH. In the present study an effort has been made to explore the codon bias perspective of this potential enzyme using bio...

Itaconic acid (IA) is a dicarboxylic acid included in the US Department of Energy's (DOE) 2004 list of the most promising chemical platforms derived from sugars. IA is produced industrially using liquid-state fermentation (LSF) by Aspergillus terreus with glucose as the carbon source. To utilize IA production in renewable resource-based biorefinery, the present study investigated the use of lig...

Non toxic zinc oxide (ZnO) nanoparticles were synthesized using a novel soil fungus, Aspergillus terreus VIT 2013. Production of these particles in fungal filtrate was observed by a change in colour from yellow to whitish yellow, along with a white precipitate which settled to the bottom of the flasks after three days. For confirming their presence through UV spectral studies, the filtrate was ...

Production cost of enzyme is largely determined by the type of the strain and raw material used to propagate the strain. Hence, selection of the strain and raw materials is crucial in enzyme production. For Glucose oxidase (GOx), previous studies showed Aspergillus terreus UniMAP AA-1 offers a better alternative to the existing sources. Thus, a lower production cost could be logically anticipat...

Three fungal strains were found to be capable of bioleaching rare earth elements from monazite, a rare earth phosphate mineral, utilizing the monazite as a phosphate source and releasing rare earth cations into solution. These organisms include one known phosphate solubilizing fungus, Aspergillus niger ATCC 1015, as well as two newly isolated fungi: an Aspergillus terreus strain ML3-1 and a Pae...

We compared the in vitro pharmacodynamics of amphotericin B, itraconazole, and voriconazole against Aspergillus, Fusarium, and Scedosporium species with a combination of two non-culture-based techniques: the tetrazolium salt 2,3-bis-(2-methoxy-4-nitro-5-[(sulfenylamino)carbonyl]-2H-tetrazolium-hydroxide) (XTT) colorimetric reduction assay, and fluorescent microscopy with the cellular morbidity ...
