Parasexual Analysis of Aspergillus parasiticus

Microbiology, 1983
SUMMARY: Ten genetic markers were located on six linkage groups in Aspergillus parasiticus by means of the parasexual cycle. Diploids, selected by complementation of spore colour and auxotrophic markers, were subjected to induced haploidization by treatment with benlate.

The sexual state ofAspergillus parasiticus

Mycologia, 2009
The sexual state of Aspergillus parasiticus, a potent aflatoxin-producing fungus within section Flavi, is described. The production of nonostiolate ascocarps surrounded by a separate peridium within the stroma places the teleomorph in genus Petromyces. Petromyces parasiticus differs from P.

Nanosilica synthesis mediated by Aspergillus parasiticus strain

Fungal Biology, 2018
Rice husks (RHs) are plant waste materials abundant in phytoliths silica bodies. These were used as starting material for fungal-mediated biotransformation leading to the synthesis of a high-value added product. A strain of Aspergillus parasiticus was capable of transforming the amorphous silica conglomerates into structured nanoparticles (NPs) in the ...

Parasiticol: new metabolite from Aspergillus parasiticus

Journal of Agricultural and Food Chemistry, 1970
Parasiticol, a metabolite structurally related to the aflatoxins, has been isolated and characterized. The compound is elaborated by several strains of the Aspergillus flavus series previously shown to be aflatoxin producers. The metabolite was separated and purified by chromatography on three columns (silicic acid, silica gel, and alumina) followed by

Thermal Inactivation of Conidia From Aspergillus flavus and Aspergillus parasiticus

Journal of Milk and Food Technology, 1975
Thermal resistance at 45, 50, 55, and 60 C of conidia from various strains of Aspergillus flavus and Aspergillus parasiticus was determined using a heating menstruum buffered at pH 7.0 with KH2PO4-NaOH. Heat resistance of conidia from both molds was strain-dependent.

Aflatoxin production by entomopathogenic isolates of Aspergillus parasiticus and Aspergillus flavus

Journal of Invertebrate Pathology, 1990
Fourteen isolates of Aspergillus parasiticus and 2 isolates of Aspergillus flavus isolated from the mealybug Saccharicoccus sacchari were analyzed for production of aflatoxins B1, B2, G1, and G2 in liquid culture over a 20-day period. Twelve Aspergillus isolates including 11 A. parasiticus and 1 A.

Aspects of parasexual analysis in Aspergillus parasiticus

Canadian Journal of Microbiology, 1980
A scanning electron microscopic examination of the surface ornamentation of haploid, heterokaryotic, and diploid conidiospores of Aspergillus parasiticus is presented. Previous studies on the parasexual cycle in this aflatoxin-producing species have shown that heterozygous diploids may be isolated with ease.

Generation of aflR disruption mutants of Aspergillus parasiticus

Applied Microbiology and Biotechnology, 2000
The aflR gene of Aspergillus parasiticus and A. flavus encodes a binuclear zinc-finger, DNA-binding protein, AflR, responsible for activating the transcription of all known aflatoxin biosynthetic genes including itself. Studies to determine how environmental and nutritional factors affect aflR expression and hence aflatoxin production in A. parasiticus
