Metabolism of progesterone by Aspergillus fumigatus

Journal of Steroid Biochemistry, 1982
Abstract Metabolism of progesterone by a typical strain of Aspergillus fumigatus was studied. The four metabolites isolated were characterized as 5α-pregnane-3s-ol-20-one, 15s-hydroxy-1,4-pregnadiene-3,20-dione, 7s,15s-dihydroxy-4-pregnene-3,20-dione and 11α,15s-dihydroxy-4-pregnene-3,20-dione by the application of various spectrometric techniques.

Biodegradation of anthracene by Aspergillus fumigatus

Journal of Hazardous Materials, 2011
An anthracene-degrading strain, identified as Aspergillus fumigatus, showed a favorable ability in degradation of anthracene. The degradation efficiency could be maintained at about 60% after 5d with initial pH of the medium kept between 5 and 7.5, and the optimal temperature of 30 °C.

Developmental regulators in Aspergillus fumigatus

Journal of Microbiology, 2016
The filamentous fungus Aspergillus fumigatus is the most prevalent airborne fungal pathogen causing severe and usually fatal invasive aspergillosis in immunocompromised patients. This fungus produces a large number of small hydrophobic asexual spores called conidia as the primary means of reproduction, cell survival, propagation, and infectivity.

Itraconazole resistance in Aspergillus fumigatus

Antimicrobial Agents and Chemotherapy, 1997
Invasive aspergillosis is an increasingly frequent opportunistic infection in immunocompromised patients. Only two agents, amphotericin B and itraconazole, are licensed for therapy. Itraconazole acts through inhibition of a P-450 enzyme undertaking sterol 14alpha demethylation.

Production of melanin by Aspergillus fumigatus

Journal of Medical Microbiology, 2004
Melanins, or melanin-like compounds, may play a role in the pathogenesis of a number of human fungal infections. This study investigated the production of melanin by the important opportunistic pathogen Aspergillus fumigatus. Conidia from A. fumigatus were harvested and treated with proteolytic enzymes, denaturant and hot, concentrated acid; this ...

Metabolomics ofAspergillus fumigatus

Medical Mycology, 2009
Aspergillus fumigatus is the most important species in Aspergillus causing infective lung diseases. This species has been reported to produce a large number of extrolites, including secondary metabolites, acids, and proteins such as hydrophobins and extracellular enzymes.

Sequencing the Aspergillus fumigatus genome

The Lancet Infectious Diseases, 2002
Aspergillus fumigatus is the most common mould pathogen of human beings and unusually causes both invasive disease in immunocompromised patients and allergic disease in patients with atopic immune systems. 4% of patients dying in modern European teaching hospitals have invasive aspergillosis and it is the leading infectious cause of death in leukaemia ...

Aspergillus fumigatus DHN-Melanin

2020
Dihydroxynaphthalene melanin (DHN-melanin) is an integral component of the conidial cell wall surface, which has a central role in the pathogenicity of the major human airborne fungal pathogen Aspergillus fumigatus. Although the biosynthetic pathway for A.

Effects of fungicides on Aspergillus fumigatus

Antonie van Leeuwenhoek, 1979
Aspergillus fumigatus was the most frequently isolated thermophilous fungus from green leaf surfaces. The application of fungicides significantly reduced the frequency of its occurrence there. A. fumigatus was relatively tolerant to fungicides. On Captan-, Thiram-, and Verdasan-treated leaves, A.

Insertional mutagenesis of Aspergillus fumigatus

Molecular and General Genetics MGG, 1998
We have investigated transformation with heterologous DNA as a method for insertional mutagenesis of Aspergillus fumigatus. Two methods, polyethylene glycol-mediated transformation of protoplasts and electroporation of germinating spores, were used to establish conditions leading to single-copy integration of transforming DNA at different genomic sites.
