Biocontrol of Aspergillus Flavus and Aflatoxin B1 Production in Corn

The potent mycotoxin aflatoxin B1 is a secondary metabolite of Aspergillus fungi that grow, on a variety of food and feed commodities at any stage during growth, harvest, storage and transportation. The occurrence of aflatoxin contamination is global, with severe problems especially prevalent in developing countries. In present study, corn samples were contaminated with aflatoxin B1 in the conc...

Studies on an Actinomycete Producing a Melanin Pigment Inhibiting Aflatoxin B1 Production by Aspergillus flavus

Thirty different isolates of actinomycetes collected from different localities in Gharbia Governorate, Egypt were tested for melanin pigment production. Only one isolate produced melanin and identified as Streptomyces torulosus. The selected actinomycete isolate was grown under different cultural conditions and it was found that starch-nitrate medium was the optimum for the growth of selected i...

Efficacy 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...

Effect of Spices on the Growth of Aspergillus flavus and Aflatoxin B1 Production

Since the discovery of AFB1 as an important mycotoxin in 1960, several investigations have attempted to develop methods for the degradation and removal of mycotoxins from food and feed. The use of chemical preservatives in food to abate the mycotoxin problem has disadvantages due to residual effects of these preservatives on human and animal health (Freedman 1980; Parke and Lewis 1992; Knezevic...
