Abstract/OtherAbstract:
|
Nine different species of Aspergillus were isolated from the phylloplane of stored chewing tobacco (Nicotiana tobaccum) of different ages. The maximum number of species were isolated from 12 and 18 month old leaves. A. ruber, A. ochraceus, A. flavus and A. nidulans were usually associated with older leaves while A. niger, A. fumigatus and A. flavus were isolated from 6 month old leaves. Approximately 18% of Aspergilli were found to be mycotoxigenic. Sterigmatocystin was produced by three different species. A. ochraceus produced patulin and ochratoxin. All aflatoxigenic strains of A. flavus produced aflatoxin B1 but none of the isolates of A. flavus produced aflatoxin G2. The percentage of toxigenic isolates of different species varied considerably. |
