Overview

Reveals killer yeasts’ antifungal potential in ant gardens, suggesting ecological significance.

Key Points

  • This research aimed to identify killer yeast species in fungus gardens and assess their antifungal properties.
  • Surveyed fungus gardens of attine ants in Brazil for killer toxin-producing yeasts.
  • Isolated 59 yeast species and tested their antifungal activities.
  • Sequenced the genome of Candida sinolaborantium to identify new killer toxins.
  • Identified 10 killer yeast species out of 59 surveyed.
  • Killer yeasts effectively inhibited yeasts from other environments more than those from the same environment.
  • Candida sinolaborantium showed antifungal activities against 57% of tested yeast strains, identifying a new toxin named Ksino.
