RESUMO
Three yeast isolate candidates for a novel species were obtained from rotting wood samples collected in Brazil and Colombia. The Brazilian isolate differs from the Colombian isolates by one nucleotide substitution in each of the D1/D2 and small subunit (SSU) sequences. The internal transcribed spacer (ITS) and translation elongation factor 1-α gene sequences of the three isolates were identical. A phylogenetic analysis showed that this novel species belongs to the genus Ogataea. This novel species is phylogenetically related to Candida nanaspora and Candida nitratophila. The novel species differs from C. nanaspora by seven nucleotides and two indels, and by 17 nucleotides and four indels from C. nitratophila in the D1/D2 sequences. The ITS sequences of these three species differ by more than 30 nucleotides. Analyses of the sequences of the SSU and translation elongation factor 1-α gene also showed that these isolates represent a novel species of the genus Ogataea. Different from most Ogataea species, these isolates did not assimilate methanol as the sole carbon source. The name Ogataea nonmethanolica sp. nov. is proposed to accommodate these isolates. The holotype of Ogataea nonmethanolica is CBS 13485T. The MycoBank number is MB 851195.
