Abstract

Twenty-six genera and Sixty-six species, in addition to two varieties of Aspergillus nidulans and one variety of Humicola grisea were isolated from 80 peanut seed (uncovered or covered within shell at the time of sampling) samples and 40 samples of shells collected from different places in Egypt.

At 28 °C, the broadest spectrum of genera and species was recorded in the shells (21 genera and 53 species), followed by the naked seeds (16 genera and 38 species) and the covered seeds (17 genera and 33 species). Aspergillus and Penicillium were regularly the most common genera in the three substrates. A. niger, A. fumigatus, A. flavus A. terreus, A. ochraceus and P. funiculosum were generally the most common fungal species recovered from the three substrates. A. flavus was represented in 80%, 60% and 80% of the samples constituting 16.1%, 8.4% and 27.2% of the total count of fungi of the shells, covered and uncovered seeds respectively.

At 45 °C, nine genera and sixteen species were collected of which Aspergillus fumigatus was extremely dominant in the three substrates, followed by A. terreus and A. niger. Penicillium was completely eliminated.
