The Presence of 3-Hydroxy Oxylipins on the Ascospore Surfaces of Some Species Representing Saccharomycopsis Schiönning

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.
