The frequency and the density of the species associated with grape sour rot in different cultivars were determined. The most frequent species in the rotten grapes, Candida krusei, Kloeckera apiculata, and Metschnikowia pulcherrima, and a less frequent species, Issatchenkia occidentalis, when inoculated with Saccharomycopsis crataegensis were able to induce in vitro the symptoms of the disease. The gas chromatographic determination of the volatile compounds in the headspace was used to evaluate the metabolic role of the different species associated with the disease. These analyses made it possible to presume that, whereas some species, such as Candida krusei and Hanseniaspora uvarum, can be considered responsible for these modifications and in particular for the ethyl acetate production, others, such as Saccharomycopsis crataegensis, can promote the development of the former species.
测定了不同品种与葡萄酸腐病相关的物种的频率和密度。在腐烂的葡萄中最常见的物种有克鲁维酵母、尖端克鲁维酵母和膜醭毕赤酵母,以及不太常见的物种威克汉姆酵母,当与酿酒酵母共接种时,能够在体外诱导疾病的症状。利用顶空的挥发性化合物的气相色谱测定来评估与疾病相关的不同物种的代谢作用。这些分析使得可以假定,虽然一些物种,如克鲁维酵母和葡萄汁有孢汉逊酵母,可以被认为是这些变化,特别是乙酸乙酯产生的原因,而其他物种,如酿酒酵母,可以促进前者的发展。
