Mutant of Aspergillus flavus producing more aflatoxin B2 than B1.
A mutant of Aspergillus flavus having a high and relatively stable aflatoxin B2/B1 ratio was recovered after treatment with nitrosoguanidine.
متن کاملCulture characteristics and aflatoxin producing strains of Aspergillus flavus from maize grains
Accepted: 21-03-2015 The known mycotoxin the most important which have been studied mostly because of possible hazards to human health are the afltoxins.Aflatoxins produced very commonly by two species of Aspergillus viz. Aspergillus flavus and Aspergillus parasitic. In this study growth pattern and culture characteristics of Aspergillus flavus isolates were studied. Twelve strains of A. flavus...
متن کاملAflatoxin-producing strains of Aspergillus flavus detected by fluorescence of agar medium under ultraviolet light.
The fluorescence method of detecting aflatoxin-producing strains of Aspergillus flavus and related species utilizes the ultraviolet-induced fluorescence of aflatoxin produced in a modified Czapek's solution agar containing corn steep liquor, HgCl(2), and (NH(4))H(2)PO(4) instead of NaNO(3). The presence of aflatoxin is confirmed by thin-layer chromatography of CHCl(3) extracts of the fluorescin...
متن کاملEfficacy of Euphorbia splendens and Leonotis nepetaefolia on aflatoxin producing fungi Aspergillus flavus and Aspergillus parasiticus.
Efficacy of three different concentrations (5, 10 and 15 mg/ml) of dry flower powder of E. splendens and L. nepetaefolia was tested on the growth of aflatoxin-producing toxigenic strains of fungi A. flavus (NCBT 101) and A. parasiticus (NCBT 128) in Sabouraud dextrose agar medium (SDA). Maximum (75%) inhibition of growth of A. flavus was seen at 15 mg/ml concentration of E. splendens flower dry...
متن کاملEffects of Medicinal Plant Extracts and Photosensitization on Aflatoxin Producing Aspergillus flavus (Raper and Fennell)
This study was undertaken with an aim of exploring the effectiveness of medicinal plant extracts in the control of aflatoxin production. Antifungal properties, photosensitization, and phytochemical composition of aqueous and organic extracts of fruits from Solanum aculeastrum, bark from Syzygium cordatum, and leaves from Prunus africana, Ocimum lamiifolium, Lippia kituiensis, and Spinacia olera...
