Aspergillus flavus and Aspergillus ochraceus as producers of hemostaticaly active proteins

, 2018
Determination of hemostatic proteins is important branch of diagnostic medicine. New direction in the use of micromycetes enzymes is the development of diagnosticums for determining the key components of the hemostasis system, that is cheaper and more available than now used proteases isolated from the human bloodstream, recombinant proteins or native ...

Mycoremediation potential of Aspergillus ochraceus NRRL 3174

Archives of Microbiology, 2021
Mycoremediation is an important process that targets the removal of petroleum hydrocarbons by fungi. Fungi have advantages with their extensive enzymatic systems, rapid adaptation to toxic organic pollutants, and to adverse environmental conditions.

Transformation in Aspergillus ochraceus

Current Microbiology, 1995
Mutants (lysine requiring) of Aspergillus ochraceus were kept under starvation conditions for 15 days and finally were treated with DNA of a 40-h-old culture of the wild strain. The donor DNA-treated mutant conidia were then grown on plates containing minimal medium at 28 degrees C for 4 days.

Proteome analysis of Aspergillus ochraceus

Mycotoxin Research, 2010
Genome sequencing for many important fungi has begun during recent years; however, there is still some deficiency in proteome profiling of aspergilli. To obtain a comprehensive overview of proteins and their expression, a proteomic approach based on 2D gel electrophoresis and MALDI-TOF/TOF mass spectrometry was used to investigate A. ochraceus.

Biosynthesis of ochratoxins by Aspergillus ochraceus

Phytochemistry, 2001
Shaken liquid fermentation of an isolate of Aspergillus ochraceus showed growth-associated production of ochratoxins A and B, followed by production of a related polyketide diaporthin. Later, between 150 and 250 h, mellein accumulated transitorily.

Production of Ochratoxin A by Aspergillus Ochraceus

European Journal of Plant Pathology, 2004
The effects of growth conditions, trace metals, carbon and nitrogen source on ochratoxin A (OTA) production by Aspergillus ochraceus NRRL 3174 were investigated in submerged liquid culture medium. No correlation between biomass production and OTA synthesis was observed.

Amplification and diversity analysis of ketosynthase domains of putative polyketide synthase genes inAspergillus ochraceus andAspergillus carbonarius producers of ochratoxin A [PDF]

Molecular Nutrition and Food Research, 2006
The diversity of polyketide synthase (PKS) genes in Aspergillus ochraceus NRRL 3174 and Aspergillus carbonarius 2Mu134 has been investigated using different primer pairs previously developed for the ketosynthase (KS) domain of fungal PKSs. Nine different

Biosynthesis of diaporthin and orthosporin by Aspergillus ochraceus

Phytochemistry, 2001
Diaporthin and orthosporin were characterised from the fungus Aspergillus ochraceus D2306. Diaporthin was identified by high-resolution electron impact mass spectrometry and 1H and 13C NMR spectroscopy, from which new spectroscopic assignments were made.

Transformation of xanthohumol by Aspergillus ochraceus

Journal of Basic Microbiology, 2013
Microbial transformation of xanthohumol isolated from agro‐residue (spent hops), by Aspergillus ochraceus was investigated. A new aurone, (Z)‐2″‐(‐hydroxyisopropyl)‐dihydrofurano[4″,5″:6,7]‐3′,4′‐dihydroxy‐4‐methoxyaurone, was obtained as a main transformation product. Three minor metabolites were identified as 2″‐(‐hydroxyisopropyl)‐dihydrofurano[4″,5″

Allergic Bronchopulmonary Aspergillosis Caused by Aspergillus ochraceus

American Journal of Clinical Pathology, 1978
A case with the characteristics of allergic bronchopulmonary aspergillosis is described. The species of Aspergillus involved, A. ochraceus, has not previously been found in this disorder. The organism had antigenic properties distinct from five other species of Aspergillus most commonly associated with allergic bronchopulmonary aspergillosis.
