Bandoniozyma gen. nov., a genus of fermentative and non-fermentative tremellaceous yeast species

Abstract

Background: Independent surveys across the globe led to the proposal of a new basidiomycetous yeast genus within the Bulleromyces clade of the Tremellales, Bandoniozyma gen. nov., with seven new species. Methodology/Principal Findings: The species were characterized by multiple methods, including the analysis of D1/D2 and ITS nucleotide sequences, and morphological and physiological/biochemical traits. Most species can ferment glucose, which is an unusual trait among basidiomycetous yeasts. Conclusions/Significance: In this study we propose the new yeast genus Bandoniozyma, with seven species Bandoniozyma noutii sp. nov. (type species of genus; CBS 8364T = DBVPG 4489T ), Bandoniozyma aquatica sp. nov. (UFMG-DH4.20T = CBS 12527T = ATCC MYA-4876T ), Bandoniozyma complexa sp. nov. (CBS 11570T = ATCC MYA-4603T = MA28aT ), Bandoniozyma fermentans sp. nov. (CBS 12399T = NU7M71T = BCRC 23267T ), Bandoniozyma glucofermentans sp. nov. (CBS 10381T = NRRL Y-48076T = ATCC MYA-4760T = BG 02-7-15-015A-1-1T ), Bandoniozyma tunnelae sp. nov. (CBS 8024T = DBVPG 7000T ), and Bandoniozyma visegradensis sp. nov. (CBS 12505T = NRRL Y-48783T = NCAIM Y.01952T ).
