Wickerhamomyces bovis type strain was found to secrete a mycocin with a fungistatic effect at pH from 3.5 to 6.0. The peak of its activity occurred at pH 5.0 in the presence of 3% NaCl. Yeast species sensitive to this mycocin were located within the family Wickerhamomycetaceae and belonged to phylogenetically related genera Ambrosiozyma, Nakazawaea, Ogataea, and Peterozyma. 

An Updated Global Species Diversity and Phylogeny in the Genus Wickerhamomyces with Addition of Two New Species from Thailand

Phylogenetic analyses of a combination of the internal transcribed spacer region and the D1/D2 domains of the large subunit of ribosomal DNA genes support that W. lannaensis and W. nanensis are distinct from other species within the genus Wickerhamomyces.

Antagonistic Interactions and Killer Yeasts

Release of killer toxins might benefit both the toxin producer and the selfish genetic element in the producer cell, so as to provide a positive selection mechanism for the genetic system encoding both toxin and immunity.
