Identification of Penicillium aurantiogriseum species with a method of polymerase chain reaction-restriction fragment length polymorphism

A polymerase chain reaction method, added of restriction fragment length polymorphism analysis, was utilised to identify moulds, isolated from foods, belonging to Penicillium aurantiogriseum species. Suitable restriction enzymes were found. This simple method could be useful to face mycotoxin problem, discriminating toxic from non-toxic strains.
