Genomic characterization of a novel partitivirus infecting Aspergillus ochraceus
Virus Genes, 2008Three double-stranded RNA (dsRNA) segments from Aspergillus ochraceus isolate FA 0611, designated as AoR1, AoR2, and AoR3, were cloned and sequenced. AoR1 was identical with AoV dsRNA 1 previously reported from A. ochraceus ATCC 28706, which putatively encoded an RNA-dependent RNA polymerase of an unidentified mycovirus.

Steroid 11-Alpha-Hydroxylation by the Fungi Aspergillus nidulans and Aspergillus ochraceus
2017Steroids are a group of natural compounds derived from the cyclopentane-perhydro-phenantrene nucleus that have a great interest for the pharmaceutical industries as a consequence of their physiological effects. Among their functions are anti-inflammatory, immunosuppressive, or contraceptive activities.

The component fatty acids of Aspergillus ochraceus fat
Journal of the Science of Food and Agriculture, 1973AbstractAspergillus ochraceus, grown as a surface culture in a chemically defined medium of sucrose and inorganic salts, gave a high yield of fat (47.5%) the main component acids of which were shown to be myristic (0.2%); palmitic (37.6%); stearic (0.1%); oleic (14.6%); linoleic (45.3%); and linolenic (2.2%).

Biodegradation of kerosene by Aspergillus ochraceus NCIM‐1146
Journal of Basic Microbiology, 2007AbstractThe filamentous fungus Aspergillus ochraceus NCIM‐1146 was found to degrade kerosene, when previously grown mycelium (96 h) was incubated in the broth containing kerosene. Higher levels of NADPH‐DCIP reductase, aminopyrine N‐demethylase and kerosene biodegradation activities were found to be present after the growth in potato dextrose broth for

Continuous hydroxylation of progesterone byAspergillus ochraceus
Antonie van Leeuwenhoek, 1961In this paper are presented the results of experiments undertaken to determine what conditions are necessary for the hydroxylation of progesterone during continuous culture ofAspergillus ochraceus NRRL 405. It was found possible to operate with either one or two stages, but because of the inhibitory effect of progesterone on the growth of the ...

International Journal of Food Microbiology, 2005
Two PCR assays have been developed to detect Aspergillus carbonarius and Aspergillus ochraceus, considered the main sources of ochratoxin A (OTA) contaminating commodities, particularly grapes, coffee and derivatives, in warm climates. The species specific primers have been designed on the basis of ITS (internal transcribed spacers of rDNA units ...

Isolation of secondary metabolites of Aspergillus ochraceus by HPLC
Mycotoxin Research, 1986A method is described for the isolation and purification of ochratoxin A, ochratoxin B, ochratoxin ß mellein, 4-hydroxymellein and penicillic acid produced byAspergillus ochraceus in a synthetic liquid medium. Ochratoxin α, which was not found in the culture medium, was obtained by acid hydrolysis of ochratoxin A.

Purification and Properties of Rennin-like Enzyme from Aspergillus ochraceus
Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Mikrobiologie der Landwirtschaft, der Technologie und des Umweltschutzes, 1978An active milk-clotting enzyme was purified some 40-fold from culture supernatant of Aspergillus ochraceus. The purification steps included ammonium sulfate precipitation, G-100 Sephadex gel filtration, and ion exchange chromatography, using DEAE Cellulose column. The enzyme exhibited milk-clotting activity and proteolytic behaviour, an optimum at pH 6.

[Thrombolytic and pharmacodynamic properties of Aspergillus ochraceus protease].
Farmakologiia i toksikologiia, 1976The protease isolated from Aspergillus ochraceus exerts a strong thrombolytic action. In in vitro experiments and in tests with animals (mice, rats, dogs) it caused lysis of fibrinous clots. The thrombolytic effect of the protease is conditioned by its direct influence on the fibrin.
