Study on the presence of ochratoxin α in cultures of ochratoxigenic and non- ochratoxigenic strains of Aspergillus carbonarius
Ochratoxin A (OTA) is a potent nephrotoxin and carcinogen which is found in a wide variety of common foods and beverages and it is produced by several species of Aspergillus and Penicillium. Ochratoxin α (OTα), a major metabolite of OTA, has also been reported to occur in cultures of OTA-producing species. However there is some controversial about the participation of OTα in the biosynthesis of...
متن کاملEffect of water activity and temperature on growth of ochratoxigenic strains of Aspergillus carbonarius isolated from Argentinean dried vine fruits.
Aspergillus carbonarius is an ochratoxin A (OTA) producing fungus, predominantly responsible for the production of this mycotoxin in grapes, wine and dried vine fruits. The objective of this study was to determine the in vitro effects of water activity (a(w), 0.80-0.95) and temperature (15-35 degrees C) on lag phase extension and radial growth rate of a cocktail inoculum of four strains of A. c...
متن کاملFunctional Characterization of the alb1 Orthologue Gene in the Ochratoxigenic Fungus Aspergillus carbonarius (AC49 strain)
Aspergillus carbonarius, belonging to the group Nigri, is the main species responsible for contamination by ochratoxin A (OTA) in grapes and derivative products. OTA can accumulate in the mycelium and in black conidia of the fungus and released into the matrix. Here, we have deleted in A. carbonarius the alb1 orthologue gene of A. fumigatus, involved in melanin biosynthesis. Three A. carbonariu...
متن کاملUltraviolet-C and induced stilbenes control ochratoxigenic Aspergillus in grapes.
This study investigated the efficacy of ultraviolet-C (254 nm) and induced stilbenes to inhibit Aspergillus carbonarius and Aspergillus tubingensis and control ochratoxin A production in grapes. In addition, the stilbene synthesis as a response to UV-C treatment and to infection of ochratoxigenic Aspergillus was compared. The initial microbial inactivation by a previously optimized UV-C illumin...
متن کاملBAOJ Microbiology Molecular Affirmation of Aspergillus luchuensis a Niger Group Species as a Non- Ochratoxigenic Fungus
Amongst the various species of Aspergillus section Nigri; Aspergillus luchuensis, associated with food and beverage fermentation in East Asia, is evaluated by multiple researchers as nonochratoxigenic based on the extrolite analysis. Beyond extrolite analysis, in the present study, A. luchuensis strain was analyzed by a rapid Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (P...
