Abstract

Two novel yeast species, sp. nov. and sp. nov., were isolated from bromeliads in Itapuã Park, Rio Grande do Sul, Brazil. These species are genetically isolated from all other currently recognized ascomycetous yeasts based on their sequence divergence in the D1/D2 domain of the LSU rRNA gene. sp. nov. is phylogenetically close to , a species also isolated from bromeliads in Brazil, but the novel species can be differentiated on the basis of differences in the D1/D2 domain and positive results for the assimilation of -arabinose, raffinose, inulin and citrate. sp. nov. is phylogenetically placed in a clade near that is composed of several species associated with insects, but the novel species can be differentiated from them by the D1/D2 and ITS gene sequences, positive results for the assimilation of nitrite and a negative result for the assimilation of ethylamine. The type strain for sp. nov. is BI153 (=CBS 10831=NRRL Y-48456) and the type strain for sp. nov. is BI146 (=CBS 10829=NRRL Y-48461).
