Kluyveromyces is a genus of ascomycetous yeasts in the family Saccharomycetaceae.

The genus name of Kluyveromyces is in honour of Albert Jan Kluyver ForMemRS (1888-1956), who was a Dutch microbiologist and biochemist.

Mating and sporulation in Kluyveromyces are co-induced by poor environments and most often occur in succession without intervening diploid mitotic cell divisions.

[4] A RAD52 gene homolog from Kluyveromyces lactis was cloned and characterized.

[5] This gene, which has a central role in recombinational repair of DNA, can complement S. cerevisiae rad52 mutants.
