Abstract

Two new yeast species of the genus Ambrosiozyma are described on the basis of comparison of nucleotide sequences of large subunit of ribosomal DNA D1/D2 region. Ambrosiozyma kamigamensis and Ambrosiozyma neoplatypodis differ from Ambrosiozyma ambrosiae by 17 nucleotides (3.0%) and 16 nucleotides (2.8%), respectively, out of 565. The two species differ from each other by 13 nucleotides. Ambrosiozyma kamigamensis was isolated from galleries of the ambrosia beetle, Platypus quercivorus, in specimens of Quercus laurifolia and Castanopsis cuspidata located in the southern part of Kyoto, Japan. Ambrosiozyma neoplatypodis was isolated from similar material, but only in Q. laurifolia. Ambrosiozyma kamigamensis can be distinguished from the other Ambrosiozyma species by the inability to assimilate erythritol, whereas A. neoplatypodis can be distinguished by the ability to assimilate both L: -arabinose and nitrate. The type strains of A. kamigamensis and A. neoplatypodis are JCM 14990(T) (=CBS 10899(T)) and JCM 14992(T) (=CBS 10900(T)), respectively. This is the first report of new Ambrosiozyma species since the genus was proposed.
