Characterization of aflatoxin producing Aspergillus flavus from food and feed samples

Aspergillus flavus is one of the major producers of aflatoxin and can contaminate wide range of agricultural commodities either in field or in storage. 15 presumptive Aspergillus flavus has been isolated from 30 feed and grain samples. All the isolates were morphologically similar to Aspergillus flavus type strains. All the isolates were found to be aflatoxigenic. DNA sequencing of 5.8 s rDNA c...

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...

Isolation and Quantification of Aflatoxin from Aspergillus Flavus Infected Rice

Isolation of Apergillus flavus from groundnut and production of aflatoxin on rice. a method has been developed for the production of aflatoxin by growing Aspergillus flavus strain AJ on the solid substrate rice. Optimal yields, more than 1mg of aflatoxin B1 per gram of starting material, were obtained in 5 days at 28C.A crude product containing aflatoxin was isolated by HPLC (High Performance L...
