In the present study the mould incidence, ergosterol and aflatoxin B1 (AFB1) contaminations were evaluated in different food based seed samples viz., chickpea, cowpea, green gram, groundnut, Indian bean, maize, sorghum, soya bean and sunflower collected from different agro-climatic regions of Karnataka (India). The agar plate and standard blotter methods were employed for determination of the f...

For most of the half century that aflatoxigenic species have been intensively studied, these molds were known only to reproduce asexually, with parasexuality found only in the laboratory between certain mutant strains. Therefore, the fairly recent discovery of their sexual (teleomorphic) states creates a new wrinkle in our understanding of the field behavior of these agriculturally significant ...

background: aflatoxin contamination of food and feed stuff is a serious health problem and significant economic concerns. in the present study, the inhibitory effect of candida parapsilosis ip1698 on mycelial growth and aflatoxin production in aflatoxigenic strains of aspergillus species was investigated. methods: mycelial growth inhibitions of nine strains of aflatoxigenic and non-aflatoxigeni...

High-performance liquid chromatography (HPLC) provides a quick and efficient tool for accurately characterizing aflatoxigenic non-aflatoxigenic isolates of Aspergillus flavus. This method also quantitative analysis AFs in The method’s recovery was assessed by spiking mixture AF at different concentrations to the testing medium. validity confirmed using strains A. HPLC system, coupled with fluor...

The aim of the present investigation was to check natural aflatoxin contamination and aflatoxigenic potential of Aspergillus flavus strains isolated from chilgoza pine nuts. Fifty eight samples of chilgoza pine nuts, randomly purchased from retail shops and local markets of different locations of Jammu, were subjected to mycological analysis for isolation of Aspergillus flavus isolates using st...

Contamination of corn, cotton, peanuts and tree nuts by aflatoxins is a severe economic burden for growers. A current biocontrol strategy is to use non-aflatoxigenic Aspergillus flavus strains to competitively exclude field toxigenic Aspergillus species. A. flavus K49 does not produce aflatoxins and cyclopiazonic acid (CPA) and is currently being tested in corn-growing fields in Mississippi. We...

Cyclo(l-Ala-l-Pro) inhibits aflatoxin production in aflatoxigenic fungi without affecting fungal growth. The mode of action of cyclo(l-Ala-l-Pro) in inhibiting aflatoxin production of Aspergillus flavus was investigated. A glutathione S-transferase (GST) of the fungus, designated AfGST, was identified as a binding protein of cyclo(l-Ala-l-Pro) in an experiment performed using cyclo(l-Ala-l-Pro)...
