title: [Mycocinogeny in Bullera genus: killer activity of Bullera unica and intragenus killer-sensitive relationships].
abstract: The killer toxin secreted by the type strain of Bullera unica is sensitive to proteases and high temperature and displays fungicidal activities in a pH range of 3.5-6. Ascomycetous yeasts are resistant to this toxin except for Lipomycetaceae and two species of debaryomycetes. This mycocin displays activity against basidiomycetous yeasts, primarily those of tremellaceous affinity. The killer phenotype of B. unica is retained after treatment with agents eliminating extrachromosomal genetic elements. Intrageneric killer-sensitive relationships among within the genus Bullera were studied using all known in this genus; the results are discussed in taxonomic terms.
