Abstract

Aspergillus niger is a significant component of the fungal community on grapes. The mycotoxinfumonisin B2 (FB2) was recently detected in grape must and wine as well as in cultures of someA. niger strains isolated from grapes and raisins. This study examined 48 strains of Aspergillus sectionNigri for the presence of the fumonisin biosynthetic gene fum8 in relation to FB2 production. The fum8gene was detected in only 11 A. niger strains, 9 of which also produced FB2. Maximum parsimonyanalysis based on the calmodulin gene sequence indicated that the presence/absence of fum8 is notcorrelated with the phylogenetic relationship of the isolates. This is the first report correlating thepresence of a fumonisin biosynthetic gene with fumonisin production in A. niger from an important foodcrop. The results suggest that the absence of FB2 production in grape isolates of A. niger can resultfrom the absence of at least one gene essential for production.
