摘      要：Diversity of yeasts in association with bees and their food sources has been explored during the last *** Thailand,there has been no study of yeast identification in honey and ***,a total of 186 yeast strains were isolated from 37 honey samples of 12 different bee *** the basis of morphological and physiological characteristics,55 representative strains were chosen and identified by sequence analysis of the 26S rDNA D1/D2 domain and the ITS *** data were compared with the published sequences and the results showed the occurrence of 19 ascomycetous and 1 basidiomycetous yeast *** strains of the new species were *** analysis of the 26S rDNA D1/D2 sequence revealed that they were conspecific and most closely related to Zygosaccharomyces *** on the ITS sequence,the new species was clustered with the typeand clearly distinguished from the type!.Sequence analysis of combined ITS-26S rDNA D1/D2 showed similar *** occurrence of these two types,with a divergence of more than 1%in their sequences,and low DNA relatedness among them suggested that members of the typeβcan be regarded as separate *** analysis of the morphological and physiological characteristics was *** formation was observed on acetate agar and Gorodkowa *** new Zygosaccharomyces species differed physiologically from *** in 4 assimilation *** data supports the hypothesis that the new species,Zygosaccharomyces siamensis,is a novel ascosporogenous *** type strain is JCM 16825T(=CBS 12273T)and a description is given here.
