Zygosaccharomyces machadoi sp. n., a yeast species isolated from a nest of the stingless bee tetragonisca angustula

Abstract

A new yeast species, Zygosaccharomyces machadoi, was discovered in garbage pellets of the stingless bee Tetragosnica angustula in Brazil. Analysis of the sequence of the D1/D2 domains of the large-subunit rDNA showed that the new species is related to Zygosaccharomyces rouxii. Z. machadoi probably causes food spoilage in hives of stingless bees. It assimilates only a few carbon sources such that it is difficult to distinguish it from other Zygosaccharomyces species based on conventional physiological tests. The type strain of Z. machadoi is UFMG-J01-63.2T (CBS10264T). © 2005 Instituto de Ciências Biológicas - UFMG.
