Resumo: | Toxigenic fungi were studied in beans (Phaseolus vulgaris L.) of Classes black and color, cultivated in different regions of the State of Santa Catarina, south region of Brazil. The mean counts of filamentous fungi were 2.8 x 103 and 6.7 x 103 CFU/g for beans Classes black and color, respectively. Penicillium spp., Aspergillus spp. and Phoma spp. were the most frequent genera isolated, followed by Ryzopus spp., Alternaria spp., Helminthosporium spp., Cladosporium spp., Botrytis spp., Fusarium spp., Trichoderma spp., Curvularia spp. and Dreschelera spp. Among beans Class black, 24.6% of the Aspergillus strains produced mycotoxins: 13.1% produced aflatoxins (AFs); 11.5% produced ochratoxin A (OTA) and 28.9% of Penicillium produced citrinin (CTR). On the other hand, 22.1% of Aspergillus strains isolated from beans Class color produced mycotoxins (16.7% produced AFs and 5.4% produced OTA), while Penicillium genera had 35.4% of CTR producing strains. The toxigenic species were A. flavus, A. parasiticus, A. ochraceus and P. citrinum Thom.
