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 کاملCyclogregatin, a new metabolite from Aspergillus panamensis.
During the course of the isolation of gregatin A (1) from submerged cultures of Aspergillus panamensis a new tetronic acid derivative was obtained. According to its cyclic structure this compound was named cyclogregatin (2). In the following the structural elucidation and the biological activities of 2 in comparison with gregatin A will be described. A. panamensis, CBS120.45, was cultivated as ...
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 کاملCharacterization of aflatoxigenic Aspergillus flavus and A. parasiticus strain isolates from animal feedstuffs in northeastern Iran
Aflatoxins are secondary toxic metabolites produced by some Aspergillus spp. particularly, Aspergillus flavus and A. parasiticus that contaminate food and feed. The objective of this study was to evaluate the contamination of feedstuffs with Aspergillus spp. and detect genes involved in the aflatoxin biosynthesis pathway of A. flavus and A. parasiticus isolates. A total of 110 cow feed samples ...
متن کاملComparison of Expression of Secondary Metabolite Biosynthesis Cluster Genes in Aspergillus flavus, A. parasiticus, and A. oryzae
Fifty six secondary metabolite biosynthesis gene clusters are predicted to be in the Aspergillus flavus genome. In spite of this, the biosyntheses of only seven metabolites, including the aflatoxins, kojic acid, cyclopiazonic acid and aflatrem, have been assigned to a particular gene cluster. We used RNA-seq to compare expression of secondary metabolite genes in gene clusters for the closely re...
