Kluyveromyces Van der Walt 1956
fungi genus in the saccharomycetaceae family
Kluyveromyces is a genus of ascomycetous yeasts in the family Saccharomycetaceae. Some of the species, such as K. marxianus, are the teleomorphs of Candida species. The genus name of Kluyveromyces is in honour of Albert Jan Kluyver ForMemRS (1888-1956), who was a Dutch microbiologist and biochemist. The genus was circumscribed by Johannes P. Van der Walt in Antonie van Leeuwenhoek vol.22 on pages 268–271 in 1956. Mating and sporulation in Kluyveromyces are co-induced by poor environments and most often occur in succession without intervening diploid mitotic cell divisions. A RAD52 gene
Yarrowia lipolytica (Wick., Kurtzman & Herman) Van der Walt & Arx 1981
fungi species in the dipodascaceae family
Yarrowia lipolytica is a species of fungus in the family Dipodascaceae. It is notable for its use of unusual carbon sources, such as hydrocarbons. This has made it of interest for use in industrial microbiology, especially for the production of specialty lipids.
Yarrowia Van der Walt & Arx 1981
fungi genus in the dipodascaceae family
Yarrowia is a fungal genus in the family Dipodascaceae. For a while the genus was monotypic, containing the single species Yarrowia lipolytica, a yeast that can use unusual carbon sources, such as hydrocarbons. Molecular phylogenetics analysis has revealed several other species that have since been added to the genus.
Kluyveromyces marxianus (E.C. Hansen) Van der Walt 1971
fungi species in the saccharomycetaceae family
Kluyveromyces marxianus in ascomycetous yeast and member of the genus, Kluyveromyces. It is the sexual stage (teleomorph) of Atelosaccharomyces pseudotropicalis also known as Candida kefyr. This species has a homothallic mating system and is often isolated from dairy products.

Saccharomycopsidaceae Arx & Van der Walt 1987
fungi family in the order saccharomycetales
The Saccharomycopsidaceae are a family of yeasts in the order Saccharomycetales. According to the 2007 Outline of Ascomycota, the family contains three genera, although the placement of the genus Ambrosiozyma is uncertain. Species in this poorly known family have a widespread distribution.
Kluyveromyces lactis (Stell.-Dekk.) Van der Walt 1971
fungi species in the saccharomycetaceae family
Kluyveromyces lactis is a Kluyveromyces yeast commonly used for genetic studies and industrial applications. Its name comes from the ability to assimilate lactose and convert it into lactic acid. Kluyveromyces lactis (formerly Saccharomyces lactis) is a yeast which has the ability to assimilate lactose and convert it into lactic acid. K. lactis and other organisms i.e., Aspergillus niger var awamori and Escherichia coli K-12 are grown in fermenters to produce chymosin (rennet) on a commercial scale; this rennet, which replaces the conventional form obtained from slaughtered animals, is now
Torulaspora globosa (Klöcker) Van der Walt & Johannsen 1975
fungi species in the saccharomycetaceae family
Torulaspora globosa is a yeast fungus in the genus Torulaspora. This species can be found in the rhizosphere and is beneficial for agricultural activities. Considered a plant growth promoting rhizobacteria, this species helps with plant health maintenance. It is important for biofuel production and is a promising biocontrol agent.
Hyphopichia Arx & Van der Walt 1976
fungi genus in the pichiaceae family
Hyphopichia is a genus of fungi within the Serinales order. The relationship of this taxon to other taxa within the order is unknown (incertae sedis), and it has not yet been placed with certainty into any family.

Kluyveromyces aestuarii (Fell) Van der Walt 1965
fungi species in the saccharomycetaceae family
Kluyveromyces aestuarii is a Kluyveromyces species of fungus occurring as a marine yeast. It was discovered in 1961 and was originally placed in the genus Saccharomyces.
