Fumonisin B(2) (FB(2)) was recently found to be produced by Aspergillus niger . When grape-derived products were subsequently analyzed, FB(2) contamination was found in raisins, must, and wine. This study evaluated 681 strains of black aspergilli species isolated from Portuguese wine grapes for FB(2) production when grown on Czapek yeast agar. FB(2) was not detected in Aspergillus carbonarius (n = 75) or Aspergillus ibericus (n = 9) strains, but it was detected in 176 (29%) of the strains belonging to A. niger aggregate (n = 597). The amount of FB(2) produced by these strains ranged from 0.003 to 6.0 mg/kg with a mean of 0.66 mg/kg. The Alentejo region had the lowest percentage (10%) of fumonisinogenic strains, whereas the Douro region had the highest percentage of fumonisinogenic strains (38%). Only 10 strains were found to produce FB(2) and ochratoxin A simultaneously.
伏马菌素 B（2）（FB（2））最近被发现由黑曲霉产生。当对葡萄衍生产品进行分析时，发现葡萄干、葡萄汁和葡萄酒中存在 FB（2）污染。本研究评估了从葡萄牙葡萄酒葡萄中分离出的 681 株黑曲霉属菌株在 Czapek 酵母琼脂上生长时产生 FB（2）的情况。未在炭黑曲霉（n = 75）或 Iberian 曲霉（n = 9）菌株中检测到 FB（2），但在属于 A. niger 聚集体的 176 株（n = 597）菌株中检测到 FB（2）。这些菌株产生的 FB（2）量从 0.003 到 6.0mg/kg 不等，平均为 0.66mg/kg。阿连特茹地区的产伏马菌素菌株比例最低（10%），而杜罗地区的产伏马菌素菌株比例最高（38%）。仅发现 10 株同时产生 FB（2）和赭曲霉毒素 A。
