Vineyard surveys of 11 wine producing grape cultivars, were carried out in sixteen vineyards, in five winemaking regions in Greece, during 2002 and 2003. The occurrence of various Aspergillus spp. in bunches of berries at setting, veraison and ripening at harvest time was investigated. Aspergillus niger aggregate and A. carbonarius were predominantly isolated from sampled berries. Although the prevailing Aspergillus spp. isolates belonged to A. niger aggregate, isolates of A. carbonarius were the most efficient ochratoxin A (OTA) producers. Of 50 tested isolates of A. carbonarius 42% produced amounts of OTA, exceeding 25 ppb, while none of the 85 isolates of A. niger aggregate tested produced above 16 ppb.
2002年至2003年期间，在希腊五个酿酒地区的16个葡萄园对11个酿酒葡萄品种进行了葡萄园调查。研究了在坐果期、转色期和收获期成熟时，各串浆果中各种曲霉属真菌的发生情况。黑曲霉聚集体和黑碳曲霉是从采样浆果中主要分离出的菌种。尽管占主导地位的曲霉属真菌分离株属于黑曲霉聚集体，但黑碳曲霉分离株是最有效的赭曲霉毒素A（OTA）生产者。在50株测试的黑碳曲霉分离株中，42%产生的OTA量超过25 ppb，而测试的85株黑曲霉聚集体分离株中没有一株产生的OTA量超过16 ppb。
