CARBOHYDRATE-COMPOSITION AND TAXONOMY OF GEOTRICHUM, TRICHOSPORON AND ALLIED GENERA

The yeast-like genera Geotrichum and Trichosporon are heterogeneous and are related with anamorphs of both ascomycetous and basidiomycetous fungi. A rearrangement can be obtained using carbohydrate composition of intact cells, studied with the aid of gas-liquid chromatography. The genus Geotrichum is restricted to ascomycetous species with a dominance of galactomannans, whereas Trichosporon is reserved for basidiomycete-like, xylose-containing species. Consequently, some new combinations are introduced in both genera. Representatives of related genera are included for comparison: e.g. Dipodascus, Hyphopichia, Cryptococcus and Filobasidium. © 1979 H. Veenman en Zonen.
