Saccharomycetales

Belongs within: Ascomycota.Contains: Endomycetaceae, Stephanoascales, Dipodascaceae, Metschnikowia, Phaffomycetaceae, Candida, Pichia, Eremotheciaceae, Saccharomyces. The Saccharomycetales are a clade of fungi mostly existing as yeasts. Their morphology is correspondingly simple so taxa are primarily identified by chemical and/or molecular data. Phylogenetically basal taxa often have cell walls containing glucose, mannose and galactose whereas more derived taxa contain glucose and mannose alone Schweigkofler… Continue reading Saccharomycetales

Pichia

Belongs within: Saccharomycetales. Pichia is a somewhat loosely defined genus of yeasts reproducing by multilateral budding from a narrow base. In a Pichia Published 8 October 2015 In my previous post, I alluded to the revolutionary effect that DNA analysis had on the classification of bacteria. A similar thing happened for the study of yeasts. Previously,… Continue reading Pichia

Metschnikowia

Belongs within: Saccharomycetales. Metschnikowia is a genus of yeasts reproducing by multilateral budding, and producing elongate asci containing one or two needle-like spores. A barely pronounceable yeast Published 7 November 2007 “Yeast” is, admittedly, not one of the most tasteful-sounding words in the English language (it’s right up there with “moist” and “sphagnum” in the category… Continue reading Metschnikowia

Stephanoascales

Belongs within: Saccharomycetales. The Stephanoascales were originally proposed as a grouping for saccharomycetous yeasts with galactose in the cell walls, but more recently restricted to a smaller group distinguished by molecular data (some species of which lack galactose). Members of the Stephanoascales lack extracellular amyloid compounds (Schweigkofler et al. 2002). <==Stephanoascales |–Stephanoascus Sm., Van de… Continue reading Stephanoascales
