Abstract

is currently divided into two varieties, one used for cheese starter cultures, var. and one ubiquitous patulin-producing variety, var. The ribosomal regions comprising the 5.8S gene and the internal transcribed spacers, ITS I and ITS II, have been analysed from 10 isolates belonging to each variety. The 10 var. isolates were separated into two groups of five on the basis of 12 base-pair differences in the ITS regions. One of the groups of var. in the following designated differed from var. here designated in just two positions, while the other group, here called differed from in 12 positions. Random Amplified Polymorphic DNA (RAPD) analysis substantiated these findings, and a comparison of secondary metabolites produced by the three groups showed that the isolates all produce Penicillium Roqueforti (PR) toxin, marcfortines and fumigaclavine A, while the isolates produce patulin, penitrem A and mycophenolic acid, as well as unidentified metabolites. produces secondary metabolites in five chromophore families including the known mycotoxins patulin and botryodiploidin. On the basis of these findings it is proposed that is reclassified into three species named and
