Through gas chromatography – mass spectrometry, the presence of oxylipins, mainly 3-hydroxy 9:1 and 3-hydroxy 10:1, was detected in Saccharomycopsis fermentans, Saccharomycopsis javanensis, and Saccharomycopsis vini. The distribution of these compounds was mapped using immunofluorescence microscopy, and they were found to be closely associated with the surfaces of aggregating ascospores.Key words: ascospores, gas chromatography – mass spectrometry, 3-hydroxy oxylipins, immunofluorescence microscopy, Saccharomycopsis, yeast.

Grâce à la chromatographie en phase gazeuse – spectrométrie de masse, nous avons détecté principalement la présence de 3-hydroxy 9:1 et de 3-hydroxy 10:1 chez Saccharomycopsis fermentans, Saccharomycopsis javanensis et Saccharomycopsis vini. La distribution spatiale de ces composés fut caractérisée à l'aide de la microscopie à immunofluorescence et s'est avérée être intimement associée à la surface d'ascospores agrégées.Mots clés : ascospores, chromatographie en phase gazeuse – spectrométrie de masse, oxylipines 3-hydroxy, microscopie à immunofluorescence, Saccharomycopsis, levures.[Traduit par la Rédaction]
