10.22376/ijpbs.2019.10.1.p1-12 Volume 7 Issue 4 2016 (October - December) The aim of this study was to identify aflatoxin producing fungi from affected corn and peanut samples collected from the storage godowns. Fungi were isolated from corn and peanuts using potato dextrose agar and modified rose bengal agar. The pure culture of the isolates were grown on differential media namely malt extract agar, czapek yeast extract agar and czapek dox agar for species identification using macro morphological characteristics. Lacto phenol cotton blue stains were used to identify fungal microscopic structures. All the fungi belonged to lessThan i greaterThan Aspergillus species lessThan /i greaterThan . The fungal isolates were tested for aflatoxin producing ability. Out of the five different lessThan i greaterThan Aspergillus species lessThan /i greaterThan isolated, two species namely lessThan i greaterThan A.flavus lessThan /i greaterThan and lessThan i greaterThan A.parasiticus lessThan /i greaterThan producedaflatoxin in the lessThan i greaterThan Aspergillus flavus parasiticus lessThan /i greaterThan agar medium (AFPA) lessThan i greaterThan and Aspergillus lessThan /i greaterThan differentiation medium (ADM).Early detection may help to bring in early management and control practices.
