Parasitical: A New Metabolite from Aspergillus parasiticus
Parasiticol, a metabolite structurally related to the aflatoxins, has been isolated and characterized. The compound is elaborated by several strains of the Aspergillus jiaDus series previously shown to be aflatoxin producers. The metabolite was separated and purified by chromatography Oll three columns (silicic acid, silica gel, and alumiua) followed by recrystallization from chlorofom,-bexane....
متن کاملA pyruvate decarboxylase gene from Aspergillus parasiticus.
A gene encoding a putative pyruvate decarboxylase (EC 4.1.1.1) was isolated from a genomic library of the filamentous fungus Aspergillus parasiticus strain SU-1. The deduced amino acid sequence showed 37% homology to PDC1 from Saccharomyces cerevisiae. Although A. parasiticus has an obligate growth requirement for oxygen, it produced ethanol in shake flask cultures indicating a response to anox...
متن کاملPurification and characterization of mannitol dehydrogenase from Aspergillus parasiticus.
Mannitol dehydrogenase, NADP specific (EC 1.1.1.138), was purified from mycelium of Aspergillus parasiticus (1-11-105 Whl). The enzyme had a molecular weight of 1.4 X 10(5) and was composed of four subunits of apparently equal size. The substrate specificity was limited to D-mannitol, D-glucitol, D-arabinitol, 1-deoxy-D-mannitol, and 1-deoxy-D-glucitol. Zinc ion was a powerful inhibitor of the ...
متن کاملThe sexual state of Aspergillus parasiticus.
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. alliaceus by its larger ascospores with finely tuberculate ornamentation. The anamorphic Aspergillus stat...
متن کاملDifferentiation of Aspergillus parasiticus from Aspergillus sojae by random amplification of polymorphic DNA.
Aspergillus parasiticus and Aspergillus sojae are two morphologically similar species belonging to the Aspergillus section flavi. A new method to distinguish the two species, the aflatoxin producer A. parasiticus and the koji mold A. sojae, was developed. Single primers with arbitrary sequences were used to generate random amplified polymorphic DNA (RAPD) markers from strains of these two speci...
