The yeast genus Yarrowia gen. nov
Antonie Van Leeuwenhoek
|January 1, 1980
Summary
The yeast Candida lipolytica, previously known by several names, is now classified in the new genus Yarrowia. Yarrowia lipolytica is the type species, and other Saccharomycopsis species are reclassified.
Area of Science:
- Mycology
- Yeast Taxonomy
- Microbial Systematics
Background:
- Candida lipolytica has a complex taxonomic history.
- Previous classifications included Endomycopsis lipolytica and Saccharomycopsis lipolytica.
- The ascigerous teleomorph requires precise genus assignment.
Purpose of the Study:
- To establish a new genus for the ascigerous teleomorph of Candida lipolytica.
- To designate Yarrowia lipolytica as the type species.
- To revise the classification of remaining Saccharomycopsis species.
Main Methods:
- Taxonomic revision based on morphological and potentially genetic data.
- Formal proposal of a new genus and species combination.
- Re-evaluation of related yeast species.
Main Results:
- A new genus, Yarrowia, has been established.
- Candida lipolytica is reclassified as Yarrowia lipolytica (Wickerham et al.) comb. nov.
- The genus Saccharomycopsis has been revised.
Conclusions:
- The establishment of Yarrowia provides a clearer taxonomic framework.
- This reclassification resolves ambiguities in yeast nomenclature.
- Further revisions within Saccharomycopsis are detailed.
