abstract = "During an investigation of the microbiology of Ghanaian cocoa fermentations, a number of yeast isolates with unusual pheno- and genotypic properties representing three possible novel species were isolated. Members of Group A divided by multilateral budding and ascospores were not produced. Group B strains produced true hyphae and ascospores were not produced. Group C representatives divided by budding and formed chains and star-like aggregates. Ascospores were not produced. Sequence analysis of the 26S rRNA gene (D1/D2 region) revealed that the Group A isolates were phylogenetically most closely related to Saturnispora mendoncae (gene sequence similarity 92.4 {\%}), Saturnispora besseyi (88.8 {\%}), Saturnispora saitoi (88.8 {\%}) and Saturnispora ahearnii (88.3 {\%}). Members of Group B were most closely related to representatives of the genera Dipodascus and Galactomyces and the asporogenous genus Geotrichum, but in all cases with 26S rRNA gene (D1/D2 region) similarities below 87 {\%}. For Group C, the most closely related species were Candida rugopelliculosa (92.4 {\%}), Pichia occidentalis (91.6 {\%}) and Pichia exigua (91.9 {\%}). The very low gene sequence similarities obtained for the three groups of isolates clearly indicated that they represented novel species. Repetitive Palindromic PCR (Rep-PCR) of the isolates and their closest phylogenetic relatives confirmed that the new isolates belonged to previously undescribed species.
