Aflatoxins: Biosynthesis and Methods of Biological Control
Aflatoxins, the naturally occurring mycotoxins are produced by many species of Aspergillus, a fungus, especially Aspergillus flavus and Aspergillus parasiticus. They contaminate several food commodities including cereals, peanuts and crops. Being highly toxic and carcinogenic in nature, the aflatoxins are reported to be involved in various health complications including liver cancer. This revie...
متن کاملExpression of aflR, veA and laeA as regulators of aflatoxins and cyclopiazonic acid biosynthesis pathway in Aspergillus flavus
In this study, the production of aflatoxin B1 (AFB1) and cyclopiazonic acid (CPA) was investigated in toxigenic and non-toxigenic Aspergillus flavus with respect to expression of aflR, veA and laeA genes that are involved to toxins production. A. flavus strains were cultured in YES broth at 28 °C for 4 days and the presence of (AFB1) and (CPA) was confirmed and measured by TLC and HPLC. The exp...

متن کاملBiosensors for Aflatoxins Detection
The availability of rapid and reliable methods for rapid determination of small molecules, as contaminants in food samples, including Aflatoxins, is an increasing need also for human health. In order to monitoring food contaminants, as Mycotoxins (MTXs) Gas Chromatographic (GC) and High Pressure Liquid Chromatography (HPLC) methods are generally utilized, due to their high detection sensibility...
متن کاملOccurrence of Aflatoxins in Food
Mycotoxins are natural contaminants in raw materials, food and feeds [1]. Aflatoxins are toxic metabolites produced by different species of toxigenic fungi, called mycotoxins. The discovery of aflatoxins dates back to the year 1961 following the severe outbreak of turkey “X” disease, in the England, which resulted in the deaths of more than 100.000 turkeys and other farm animals. The cause of t...
