Diversity of Aspergillus section Nigri species from vineyards with different agro-climatic conditions in Catalonia, Spain
A few Aspergillus section Nigri species are involved in the ochratoxin A (OTA) contamination in grapes worldwide, and its occurrence is determined by the agro-climatic conditions of each region. The aim of this study was to examine the diversity of black aspergilli isolated from grapes, soil, and ai...
