Abstract
The killer activity of selected crude toxins produced by nine Candida maltosa, Debaryomyces hansenii and Pichia anomala strains was tested at 37°C against 383 strains belonging to 19 pathogenic species of 10 genera (Candida, Clavispora, Cryptococcus, Filobasidiella, Issatchenkia, Kluyveromyces, Pichia, Saccharomyces, Stephanoascus and Trichosporon). The broad killer spectra exhibited by all crude toxins may lead to the development of new antimycotic agents against medically important yeasts.
