Abstract
Twelve aspergilli isolates were including two species Aspergillus parasiticus and A. terreus. A. parasiticus included six isolates, two isolates producing sliver nanoparticles (AgNPs) and four isolates non producing AgNPs. A. terreus enclosed six isolates with a similar description. Random amplified polymorphic DNA (RAPD) and Inter simple sequence repeats (ISSR) DNA markers were used, with the aim of genetically characterizing isolates of A. parasiticus and A. terreus to discriminate between producing and non producing AgNPs isolates. RAPD and ISSR analysis revealed a high level of genetic diversity in the Aspergillus parasiticus and A. terreus population, useful for genetic characterization. A. parasiticus and A. terreus isolates (producing and non producing AgNPs) shown in RAPD and ISSR dendrogram with a random distribution. There was no clear-cut relationship between the RAPD and ISSR markers and AgNPs production. RAPD and ISSR markers were not suitable to discriminate between producing and non producing AgNPs isolates.
