Abstract
Some more economical means of producing pure samples of aflatoxin B1 from local materials is described. Our results indicate that there is, however, no correlation between the C/N ratio of the materials investigated and the amount of aflatoxin B1 produced. Pawpaw (Carica papaya) appears the best substrate of those examined in this study.
