1.1 Enzymatic sensory detection of sterigmatocystin The development of fast and sensitive sensor for mycotoxins’ detection has drawn a great attention in resent years (Prieto-Simom, B. et al., 2007). However, to construct antiinterference biosensor for the practical samples is still challenge. Sterigmatocystin, a biogenic precursor of aflatoxin B1, has been classified as group 2B by the Interna...

introduction: aflatoxin b1 (afb1) is one of the most well-known hepatocarcinogens in humans. contamination of raw materials, used in the production of sausages and burgers, with aflatoxin producing molds can lead to increased level of aflatoxin in the final products and can impose hazards to human health. unfortunately, aflatoxin is resistant to heating and freezing processes, etc. and can rema...

this study was carried out to examine aflatoxin b1 (afb1) removal ability of four strains of lactic acidbacteria (lab). three indigenous (lactobacillus rhamnosus tmu094, lactobacillus fermentum tmu121and pedioccus pentosaceus tmu457) and a non-indigenous (labacillus rhamnosus ptcc1637) isolateswere studied. the strains were incubated with (afb1) at different time. the toxin residual in the supe...

Two major etiological agents, hepatitis B virus and aflatoxin B1, are considered to be involved in the induction of liver cancer in Africa. In order to elucidate any synergistic effect of these two agents we conducted a study in various parts of Kenya with different liver cancer incidence in order to establish the rate of exposure to aflatoxin and the prevalence of hepatitis infections. Of all ...

introduction: there are a lot of fungi in the air and our environment that grow and reproduce if the temperature and humidity are suitable. aspergillus flavus and parasilicus are among the most important food contaminants which have a role in food poisoning. these fungi secrete poisons which contaminate animal feed as well as the milk we get from the animals fed with these foods. methods: in th...

background: aflatoxin b1 (afb1) is a toxic metaboliteproduced by aspergillus species that contaminates a wide range ofagricultural products. objectives: this study was designed todevelop a rapid and highly sensitive immunoassay method inmicroarray format for quantitative detection of afb1 to evaluatethe potential of microarray platform for high-throughput screening,which can be beneficial in fo...

aflatoxin contamination of food and feedstuffs is a serious economic and health hazard. over a period of two years, 35 samples of raw pistachio nuts collected from different parts of iran were analysed for the presence of aflatoxigenic strains of the aspergillus flavus group. eighty-five isolates of a.flavus and a.parasiticuswere identified based on specific yello-orange pigment production in t...

backgrounds and objectives: to obtain information about aflatoxigenicity of isolated aspergillus flavus strains from shrimps. material and methods: forty - three isolates of aspergillus flavus from cultured green tiger shrimps of persian gulf were examined for their ability to produce aflatoxins. initially two media; aflatoxin producing ability medium and coconut agar medium were used to detect...
